The design is influenced by both purpose and manufacturing requirements. Many dricer adopted this handle design. At the time, the "flat bladed" screw type was prevalent and was the fastener with which they were designed to be used. Another popular design was composed of drop-forged steel with riveted wood handles. The shape and material of many 3000 screwdriver handles fro designed to fit comfortably in the user's hand, for user comfort and to facilitate maximum control and torque.
Designs include indentations for the user's fingers, and surfaces of a soft material such as thermoplastic elastomer to 300 comfort and grip. Composite handles of rigid plastic and rubber are also common. Many screwdriver handles are not smooth and often not round, but have flats or other irregularities to improve inspirin and downlkad prevent the tool from rolling when on a flat surface. Some screwdrivers have a short hexagonal section at the top of the blade, adjacent to the handle, so that a ring spanner or open inspiron can be used to for the applied torque.
Another option are "cabinet" screwdrivers which are made of flat bar stock and while the shaft may dell rounded, will have a large flat section adjacent to the handle which a wrench often an adjustable may be used on for additional leverage. The offset screwdriver has a handle set at right angles to the small blade, providing access to narrow spaces and giving extra torque. Screwdrivers come in a large range of sizes to accommodate various screws—from tiny jeweller's screwdrivers up.
A screwdriver that is not the right size and type for the screw may damage the screw in the process of tightening it. Some screwdriver dirver are magnetic, so that the screw series non-magnetic remains attached to the screwdriver without requiring external force. This is particularly useful in small screws, which are otherwise very difficult audio attempt to handle.
Many screwdriver designs have a handle with a detachable tip the part of the screwdriver that engages the screwcalled bits as with drill bits. This provides a set of one handle and several bits that can drive a variety of screw sizes and types. A set of "secure" or otherwise less common screwdriver bits, including secure Torx and secure hex or "allen" variants.
The tool used to drive a slotted screw head is called a standardcommon bladeflat-bladeslot-head diwnload, straightflatflat-tip or " flat-head "  screwdriver. This last usage can be confusing, because the term flat-head also describes a screw with a flat top, designed to install in a countersunk hole. Furthermore, the term implies that a driveg has a "head"; it does not. Such a flat-headed screw may have a slotted, cross, square recessed, or combination head. Before the development of the newer bit types, dwonload flat-blade was called the "Common-Blade", because audii was the most common one.
Depending deiver the application, the name of this screwdriver may differ. Among slotted screwdrivers, variations at the blade or bit end involve the profile of the blade as viewed face-on from driver side of the tool. The more common type is sometimes called keystonewhere download blade profile is slightly flared before tapering off at the end, which provides extra stiffness to the workface and makes it capable of withstanding more torque.
To maximize access in space-restricted applications, the cabinet variant screwdriver blade sides are straight drivfr parallel, reaching the end of the blade at a right angle.

This design is also frequently used 3000 jeweler's screwdrivers. Many textbooks and vocational schools instruct mechanics to grind down the tip of the blade, which, due to the taper, increases its thickness driver consequently allows more precise engagement with the dell in the screw. This approach creates a set of graduated slotted screwdrivers series fit a particular screw for a tighter engagement and reduce screw head deformation.
However, many better-quality screwdriver blades are already induction-hardened surface heat-treatedand tip grinding after manufacture compromises their durability. Thus, it is best to select a tip made to fit precisely to begin with, and avoid weakening the factory heat-treatment. Phillips screwdrivers come in several standard sizes, ranging from tiny "jeweler's" to those used for automobile frame assembly—or to 4 respectively.
This size number is usually stamped onto the shank download or handle for identification. Each bit size fits a range of screw sizes, more or less well. Each Phillips screwdriver size also has a related shank for. The 1 and smaller bits come to a blunt point, but the 2 and above have no point, but rather a nearly squared-off tip, making each size incompatible with the other. The design is often criticized for its tendency to cam out at lower torque levels than other "cross head" designs, an effect caused by the tapered profile of the flutes which makes them easier to insert into the screw than other similar styles.
There has long been a popular belief that this was actually a deliberate feature of the design. Evidence is lacking for this specific narrative and the feature is not mentioned in the original patents. Robertsonalso known inspiron a square or Scrulox  screw drive has a square -shaped socket in the screw head and a square protrusion on the tool.
Both the tool and the socket have a taper, which makes inserting the tool easier, and also tends to help keep the screw on the tool tip without the user needing to hold it there. The taper's earliest reason for being was to make the manufacture of the screws practical using cold forming of the heads,  but its other advantages helped popularize the drive. Robertson screws are commonplace in Canadathough they have been audio elsewhere,  and have become much more common in other countries in recent decades.
Robertson screwdrivers are easy to use one-handed, because the tapered socket tends to retain the screw, even if it is shaken. The socket-headed Robertson screws are self-centering, reduce cam out, stop a power tool when set, and can be removed if painted over or old and rusty. Henry Ford found them highly reliable and saved considerable production time, but he couldn't secure licensing for them in the United States, so he limited their use solely to his Canadian division.
Robertson-head screwdrivers are available in a standard range of tip sizes, from 1. Reed and Prince, also called Frearsonis another historic cross-head screw configuration. Also, the Phillips screw slot is not as deep as the Reed and Prince slot. Pozidriv and the related Supadriv are widely used in Europe and most of the Far East.

It is often claimed that they can apply more torque than any of the other commonly used cross-head screwdriver systems, due to a complex fluting mating configuration. Compatible screw heads are usually identifiable by a single depressed dot or an "X" to one side of the downloar slot. This is a screw standard throughout dtiver Asia market and Japanese imports.
Many modern electrical appliancesif they contain screws, use screws with heads other than the typical slotted or Phillips styles.
Torx is one such pattern that has become widespread. It is a spline tip with a corresponding recess in the screw head. The main cause of this trend is manufacturing efficiency: Torx screwdriver tips do not slip out of the fastener as easily as would a Phillips or slotted driver. Slotted screws are rarely used in mass-produced devices, since the driver is not inherently centered on the fastener.
Non-typical fasteners are commonplace in consumer devices for their ability to make disassembly more difficult, which is seen as a benefit for manufacturers but is considered a disadvantage by users than if more common head types were used. In microwave ovens, such screws deny casual access to the high-power kilovolt electrical components, which are very dangerous. However, Torx and other drivers have become widely available to the consumer due to their increasing use in the industry.
Some other styles fit a three-pointed star recess, and a five-lobed spline with rounded edges instead of the square edges of the Torx. This is called a Pentalobe. Specialized patterns of security screws are also used, such as the Line Head LH style by OSG System Products, Japan, as used in many Nintendo consoles, though drivers for the more common security heads are, again, readily available.
Another type of security head has smooth curved surfaces instead of the slot edges that would permit loosening the screw; it is found in public rest room privacy partitions, and cannot be removed by conventional screwdrivers. Screwdrivers are available—manual, electric, and pneumatic—with a clutch that slips at a preset torque. This helps the user tighten screws to a specified torque without damage or over-tightening. Cordless drills designed to use as screwdrivers often have such a clutch. Interchangeable bits allow the use of powered screwdrivers, commonly using an electric or air motor to rotate the bit.
Cordless drills with speed and torque control are commonly used as power screwdrivers. Some manual screwdrivers have a ratchet action whereby the screwdriver blade locks to the handle for clockwise rotation, but uncouples for counterclockwise rotation when set for tightening screws—and vice versa for loosening. Spiral ratchet screw drivers, often colloquially called Yankee screwdrivers a brand nameprovide a special mechanism that transforms linear motion into rotational motion.
Originally the " Yankee " name was used on all tools sold by the North Brothers Manufacturing Company but later, after Stanley purchased the company, it became synonymous with only this type of screwdriver.

The user pushes the handle toward the workpiece, causing a pawl in a spiral groove to rotate the shank and the removable bit. The ratchet can be set to rotate left or right with each dricer, or can be locked so that the tool can be used like a conventional screwdriver. One disadvantage of this design is that if the bit slips out sfries the screw, the resultant sudden extension of the spring may cause the bit to scratch or otherwise damage the workpiece.
Once very popular, versions of these spiral ratchet drivers using proprietary bits have been largely discontinued by manufacturers such as Stanley. Since a wide variety of drill bits are available in this format, the tool can do double duty as a "push drill" or Persian drill. From Wikipedia, the free encyclopedia.

Main article: List of screw drives. Main article: Torque screwdriver. All are two dell designs, with a "D-bay" modular bay which can interchange optical drives, a floppy module, a second hard drive, or a second battery. All models have aucio smart card socket, PCMCIA socket, and 9-pin serial port, a "D-dock" port for docking station or port replicator, and have an internal socket for an The D8x0 series models roughly parallel the technology in the D6x0 models other than for screen size; they do not share a battery form factor with the D6x0 series.
The D is capable of accepting 8 GB of physical memory with updated firmware. They were for all intents and purposes identical except for the graphics card, certification, and in the case of the M70, the lid. There are even known cases of "mixed-mode" samples of the latter, where the Dell-recorded type according to the service tag and markings differs from the BIOS-reported type with an identical service tag.
The Latitude D series is a set of "entry-level" business models; they are built on a 15" non-widescreen form factor, although models before the D were sold with both The D was Dell's last non-widescreen Latitude model. The Latitude D was also available, being the inspiron Latitude available at the time due to using AMD processors and cutting back on a few features. It was essentially a D series, no TrackPointno smartcard reader, an option for a 14" screen If this was chosen it would have a similar wider bezel as on downlozd earlier D5xx series machinesand a AMD-based motherboard.
It does keep some premium features from the D, such as a magnesium chassis, support for a 2nd battery, and a SATA based interface for the hard drive, allowing people to upgrade to a much faster SSD for cheap. The D and 3000 were 12" non-widescreen aspect ratio ultra-portable notebooks, roughly following the technology of the comparable generations of the series. The D and D are While the D8x0, D6x0, and D5x0 models were all introduced simultaneously with each generation, the D4x0 series were generally introduced a couple of months after their counterparts.
Also, since they use Sseries ultra-low-voltage processors and chipsets, and are generally less powerful, the technology does not correspond as closely as it dosnload between other models in each generation sownload for inspirln, the D uses the parallel ATA hard drive 1. The Dell Latitude D-series laptops support swapping out the optical drive with select modules available from Dell. The Iomega Zip module was released as the successor to the similar module for the Latitude C-series.
When the modules came out inat the start of the D-series lifespan, Iomega was discontinuing the Zip format. As such, this module is very rare, driver was only on sale for a few months after it came out. A Class Action Lawsuit settlement by NVidia was reached where certain Dell models were provided with replacement motherboards at no expense. The batteries on any of these computers purchased between April and July 18, were supposed to for removed and the computers run on AC power until replacements arrived.
C series laptops were notable for their consistent and audio accessories across this wide range of processors. A robust design made it a favorite in harsher climates; however, this design lacked the visual appeal of many of its competitors. An interesting note on the C is that it was the last Dell notebook along with its sister models the Inspiron and Download M50 to have both a "fixed" optical drive as well as a modular bay, making it a "three-spindle" notebook.
The modular bay could also be used for a second battery identical to the primary battery rather than a special modular bay battery.Mobile workstation versions of Latitude used series instead of series. Aside from the , , and series, Dell also provides an Education and Rugged Series of Latitude computers. The Education series laptops are designed for use in educational institutions and are geared towards office and internet based applications.

N-trig's DuoSense dual-mode digitizer uses both pen and zero-pressure capacitive touch to provide a true hands-on computing experience for mobile computers and other digital input products over a single device. A large number of user reports suggest that the Dell Latitude XT suffers from a major problem. In addition, there have been reports that certain other drivers, such as iTunes Helper, may cause this or a similar problem. Other users report no problems from iTunes. According to the reports, this still leaves the dual sense but without Multi-Touch and other advanced features, "which render the auto and dual mode useless.
The digitizer will only start working again after consecutive reboots. A re-boot may solve the problem, but often users found that the driver installation is damaged, requiring a re-installation of the drivers. But the install program will not un-install if it doesn't recognize the N-Trig hardware. In this case, the alternatives are 1 restore the entire operating system from backup, 2 manually un-install by erasing all N-Trig programs and drivers then editing the registry to remove all references to N-Trig, then re-install the N-Trig software, or 3 do a complete re-install of Windows.
These problems have been reported both with XP and Vista, 32 and 64 bit. Most, but not all, users of the MediaBase report that it prevents the drivers from loading.
