33 Piece Security Bit Set Tamper Proof Torx Hex Star Screwdriver

Product Information

A Torx successor, Torx Plus, was introduced around 1990 when the original Torx patent was expiring. The Torx Plus patent subsequently expired in 2011. [16] [17] The lobes are more square to allow for higher torque and to minimize wear. The name is shortened to IP (Internal Plus) with sizes ranging from 1IP to 100IP [18] (sometimes listed as IP1 to IP100 [19]) and EP (External Plus) with sizes ranging from 1EP to 42EP as well as smaller sizes ranging from H7EP to H2EP and includes five-lobed tamper-resistant variants. [18] The specifications for these licenses are held by Textron. Standard Torx drivers can be used to drive Torx Plus screws, but not to full torque because of the loose fit. Torx Plus drivers will not fit into standard Torx screws. 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. 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 ] This snug fit allows for greater torque transfer. The Torx Plus screws can be tightened more securely than their Torx counterparts. More secure installation means the workpiece is held together more securely, leading to greater durability. These fasteners also don’t wobble, so they’re suitable for applications that require high accuracy, like electronics and automobile industries. Polydrive (RIBE) What is a Polydrive Screw?

Another advantage over other types is that star bits are much more efficient when hand-tightening. You can apply a large amount of torque without camming out. The Polydrive, or RIBE, is a fastener similar to the Torx. To the untrained eye, they may even look interchangeable. These fasteners also have a spline-shaped geometry with rounded ends, cut as a recess into the fastener head, that allows secure fastening, increases torque transfer, and minimizes cam-out. Have you noticed that the effective cross-sectional size of Torx Plus is larger than the regular Torx profile? Compatibility The modified geometry improves durability and maximizes the torque available to the fastener. This increased torque allows the fastener to be fastened more securely without stripping the screw head. Sidewall Difference Using a Torx Bit Sizes Chart is a great way to know which size to buy for a specific fastener. The chart can help you understand the difference between metric and SAE, and can also tell you what size is a good fit for the job at hand. It can also help you choose between an external Torx and an inverted Torx. Torx Bit Sizes Chart

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. Technical Information on Fasteners: Design recommendations 11.1 Inside drives for screws – AW drive (AW-Antrieb)" (PDF). Adolf Würth GmbH & Co. KG . Retrieved 2 March 2017. As illustrated in the figure below, the Torx design has a 15° drive angle, while the Torx Plus features a 0° drive angle. The decreased drive angle allows for less movement of the fastener relative to the head. It eliminates radial stresses at the impact points between the head and the fastener. a b c U.S. Patent 3,584,667, Bernard F. Reiland, "Coupling arrangement and tools for same", filed 1967-03-21

Torx 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. Unlike other screwdrivers, Torx fasteners are made to be resistant to cam-out. This is a type of tampering that occurs when a torque is applied to a screw that exceeds its limit. The Torx bit creates a round hole to prevent this from occurring.

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. Construction Range Overview (Fasteners: Introducing the AW Drive System, p. 3)" (PDF). Würth New Zealand. 2016. Both Torx and Torx Plus are available on the market. What’s the difference between these two, and where are they used?

Torx screws are available in a wide range of sizes. These are indicated by the letter T or Tx, and range from less than one millimetre (T1) across the head up to T100, which is a full 22mm in size. The most common sizes are: The most common sizes are T10 and T25. The head height is 0.062 inch (1.6 mm). The head diameter is 0.50 inch (1.27 cm). Some other specialized sizes include T55 and T27. The Torx Plus drive system is another variation of the Torx. It is also known as External Plus. The lobes are more square than the original design. This design allowed for higher torque on the head. The Torx Plus also has five-lobed tamper-resistant variants. This design requires the right tools.

You can only compare up to four products at a time.

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. The angular geometry of the Torx Plus means that the fastening tool fits far more securely in the screw head.
