33 Piece Security Bit Set Tamper Proof Torx Hex Star Screwdriver

Product Information

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 ] Torx and Torx Plus are similar fasteners, but Torx Plus optimizes the design of the original Torx. While both have a six-point connection with the drive head, the Torx fastener allows for a 15° drive angle, while the Torx Plus has a 0° drive angle. This increases the available torque and minimizes wear on the fastener and drive head. This is one of those common questions where the answer is a very reserved yes. You can theoretically remove a Torx screw using a straight screwdriver or Allen key provided the two are the appropriate size. However, in both cases, you run the high risk of stripping the head. 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.

Common uses of the snake eye bolt include vehicle licence plates, building and vehicle grills, and public facilities. How to Remove Spanner Screws Tamper-Resistant TORX PLUS Drive System" (PDF).

It will tell you which Torx bits are compatible with which screws. KC Tool

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. The Polydrive fasteners are similar to the Torx system, but the geometry differs sufficiently that the drives are not interchangeable. So, a Polydrive bit can’t be used on a Torx screw, and vice versa. They do the same job, though, and their performance is comparable. Uses of Polydrive (RIBE) The Torx Ttap is perfect for applications that require secure fastening in confined spaces. Since installing the Torx Ttap fasteners can be done with one hand, you don’t need to squeeze both hands into a small space for the installation. 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.

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.

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.

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