The Ultra-Lok, and Ultra-Lok II are some of these designs that use custom keyed drivers, which tend to be confined to industrial and institutional uses that are unavailable to the average layperson. Key-Rex screws are another design, and are used in such things as ballot boxes and bank vaults. [41] Triple-square fasteners are referred to as "spline" in the UK. This is potentially confusing if looking for the more unusual 12-spline flange type. While they are distinguished under close inspection by the angle at the tip of each of the 12 points (with a 90° angle on the XZN, instead of 60°) the general similarity and ability to insert the wrong tool can cause damage to the head. While a Phillips screwdriver has slightly tapered flanks, a pointed tip, and rounded corners, a Pozidriv screwdriver has parallel flanks, a blunt tip, and additional smaller ribs at 45° to the main slots. The manufacturing process for Pozidriv screwdriver bits requires a slightly more complex cutter than that for Phillips, however both can be manufactured in four cuts from a tapered blank.

Similar to flathead screwdrivers, there are a wide range of sizes and lengths for Phillips screwdrivers and they also come in both manually driven and electric options. While Phillips screwdrivers do provide better control and driving power, the tip can still slip out of the screw head if it is driven with too much force. Go slow to ensure that the screwdriver tip grips the screw properly to avoid stripping the screw head.Hi-Torque slot drives were designed by Alcoa Fastening Systems, for situations where very high torque is needed, along with the ability to repeatedly install and remove the fastener. [7] The design features curved walls, unlike the straight-walled slot drive. TORX PLUS Tamper-Resistant Drive System". www.acument.com. Archived from the original on 2019-04-18 .

If the tool is advertised as one that's made for Apple products then it's probably going to work fine provided it's from a reputable tool maker. If you’ve ever been to a hardware store, you’ve probably seen hundreds of screwdrivers in a variety of designs, sizes, and other characteristics. Actually, the type of screwdriver you use depends entirely on the type of recess or screw drive you use. The Phillips screw drive (specified as an ANSI Type I Cross Recess [9] and type H in ISO documentation) was created by John P. Thompson, who, after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. [10] [11] Phillips is credited with forming a company ( Phillips Screw Company), improving the design, and promoting the adoption of his product. [10] The original 1932 patent [12] expired in 1966, but the Phillips Screw Company continued to develop improved designs. [10] The following are screw drives based on a cruciform shape; i.e., a cross shape. Other names for these types of drives are cross recessed, cross-head, cross tip, and cross-point. A double slotted screw drive is not considered cruciform because the shape is not recessed, and consists only of two superimposed simple milled slots. Some of these types are specified in ISO 4757, Cross recesses for screws.

Phillips screwdrivers have an X-shaped tip that is made to fit inside the X-shaped notch of a compatible Phillips head screw. These tools were developed in the 19th century as an improvement over flathead screwdrivers because the shape of the screwdriver head provides better traction or grip when you are driving or removing screws. This is one of those things that requires a little bit of money to be spent because the tool manufacturing process and material used both need to be top-notch.

A screwdriver is used for tightening or loosening the screw. A round rod with a flat end, having a handle at the other end, is called a screwdriver. The length of a screwdriver is measured, excluding the handle. The length of a screwdriver varies from 50 millimeters i.e., 2” to 18”.

The Phillips Screw Company owns the licensed product that is the Mortorq spiral drive system. The Phillips Screw Company must inspect and approve any punches, bits, and screws before they are cleared for production. Along with this "all licensees must submit samples regularly to ensure that the strict quality standards are maintained". [38] Solid modeling is used for the design of the punches, bits, and screws. Files are sent over to manufacturers containing these models so that there is no miscommunication and all the parts are the same across the board. Coin-slot drives are so-called because of the curved bottom of the recess, which facilitates driving them with a suitable coin. They are often used on items where the user is not likely to have a screwdriver when needed, such as recessed screws that attach cameras to tripod adapters, and battery compartments in some equipment such as children's toys.

Superficially it looks like a Phillips screw with narrower and more vertical slots, to give less tendency to cam out. The bottom of the recess is flat, and the point of the driver has to be blunt. A Phillips screwdriver has the same 26.5 degree cone angle but because of the tapered slots will not seat fully, and will damage the screw if forced.Remember though, don’t keep trying bits that don’t grab right away. every attempt that fails to turn it will take a little more metal from the screw. Yankee Screwdriver: Instead of using ball bearings, this screwdriver uses a spring-loaded mechanism. Instead of twisting the screw with your wrist, you place the screw head against the screw and push it to tighten. Torx Paralobe is a further improvement over Torx Plus, [48] claiming 50% increased drive system torque over Torx and 20% over Torx Plus.
