[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. Torx (pronounced / t ɔːr k s/) is a trademark for a type of screw drive characterized by a 6-point star-shaped pattern, developed in 1967 [1] by Camcar Textron. [a] A popular generic name for the drive is star, as in star screwdriver or star bits. The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal. [2] This is sometimes abbreviated in databases and catalogs as 6lobe (starting with the numeral 6, not the capital letter G). Torx Plus, Torx Paralobe and Torx ttap are improved head profiles. [3]a b c U.S. Patent 3,584,667, Bernard F. Reiland, "Coupling arrangement and tools for same", filed 1967-03-21 For the Torx type of design, the angle is much closer to 90° than in the case of the hex head, and so for a given torque the potentially damaging radial force is much lower. This property allows the head of the fastener to be smaller for the same required torque, which can be an advantage in applications where space to accommodate the head is limited.

A successor to the original Torx design was Torx Plus, introduced in 1990. This design made improvements on the original which enabled higher torque to be applied while minimizing wear. a b "TORX Drive System" (PDF). Textron Fastening Systems.

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 driverTorx screws are commonly found on automobiles, motorcycles, bicycle brake systems ( disc brakes), hard disk drives, computer systems and consumer electronics. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available; as drivers became more common, tamper-resistant variants, as described below, were developed. [4] Torx screws are also becoming increasingly popular in construction industries. We actually don’t recommend using your torx wrenches in place of a hex key or Allen wrench. However, rogue DIYers seem to think that it’s a good idea and insist on knowing the conversions. So by popular demand, we’ve created one of the first torx to hex conversion charts. From T7 to T40, we’ve provided the hex sizes that best match the most common torx sizes. Since most of our readers live in the United States, we opted to make the trox to Allen key conversions in terms of imperial sizes. With that being said, torx size, T9, won’t doesn’t really work with any of the SAE hex sizes. However, it’s actually a perfect match for metric size, 2.5 mm.
