33 Piece Security Bit Set Tamper Proof Torx Hex Star Screwdriver

Product Information

By design, Torx head screws resist cam out better than Phillips head or slot head screws. [1] Whereas the tendency of Phillips drivers to cam out under excessive torque has been listed as a feature preventing damage to the screw-head or driver, [5] Torx heads were designed to prevent cam-out. The development of better torque-limiting automatic screwdrivers for use in factories allowed this change. Rather than rely on the tool to slip out of the screw head when a desired torque level is reached (which risks damage to the driver tip, screw head, or workpiece), torque-limiting driver designs achieve a desired torque consistently. The metric system is also the standard for airplanes and boats. To make the process of repairing vehicles easier, the SAE standardized the measuring system. It's also been adopted by major vehicle manufacturing hubs in other countries. Technical Information on Fasteners: Design recommendations 11.1 Inside drives for screws – AW drive (AW-Antrieb)" (PDF).

AudiTorx is a tamper-proof fastener where a convex and smooth fastener head is topped with a break-away Torx drive that snaps off when the engineered torque is reached, leaving a rivet-like bolt head that cannot be easily removed. The main application for these fasteners is in the railroad industry. [29] External (inverted) Torx [ edit ] External Torx driver

For example, if you have a screw with TX size, then you have to use a Torx Screwdriver or drive bit of TX size only. AW drive is a hexalobular-type screw head similar to Torx, with a tapered profile to aid in centering, developed by the Würth Group in Germany. [30] It is available in five sizes: AW10, AW20, AW25, AW30 and AW40. [31] Gallery [ edit ] The Torx Plus screw is ideal for high torque transfer and low head height applications. In short, applications where the screws must be tightly fastened but also fit in a small space.

Many star bits have little improvements, such as knurled ends or ball dents to improve handle grip. While essentially the same as official Torx, these little additions tend to make third party star bits a more popular choice. Internal vs External Torx External Torx While it’s common to use the terms Torx and star interchangeably, there’s actually a bit of a difference between the two. Much like the Allen wrench, Torx is a trademarked name and refers to a specific brand, whereas star is the generic name (much like hex keys). However, there is a difference beyond just licensing. Pozi – versatile Pozidriv screws feature no less than eight points of leverage, providing significantly better grip than the more familiar Phillips headFind sources: "Torx"– news · newspapers · books · scholar · JSTOR ( March 2013) ( Learn how and when to remove this template message) Examples include vehicles, motorcycles, computer systems, bicycles, consumer electronics, and hard disc drives.
