Product Information

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 This article needs additional citations for verification.

Whether you are buying a new set of Torx tools or replacing a broken one, you will need to make sure you buy the right size. There are three standard sizes of Torx, and each one can be distinguished by the T before a number. In addition to these, there are also specialized sizes that are designed for specific uses. You can browse the chart below to find the right tool for your project.

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. L-shaped - L-key is the most common type and looks very similar to a hex key/Allen key; it's easy to use and compact. The TORX(r) Drive System was invented by Camcar Textron in 1967. It was designed to provide an alternative to the slotted-head screwdrivers of the day. The patented system is trademarked by Acumen Intellectual Properties, LLC. Other manufacturers often use the Torx name to promote their products. 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. 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.

Please note:

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. Like all other fasteners, even Torx screws are available in different sizes. They follow a special ‘T’ sizing for the internal Torx an ‘E’ sizing for the external Torx. The size of the screwdriver or the drive bit must match with the size of the Torx screw. If you need to know which size of Torx is the right one for a specific project, take a look at the Torx bit sizes chart. It will tell you which Torx bits are compatible with which screws. KC Tool Depending on your application, there are various different types of Torx keys that can be used. The most common types are: The metric system is a good fit for larger distances. It is not as accurate for smaller distances. Tamper-Proof

Torx keys are hand tools specifically designed to tighten or loosen Torx fasteners. Designed with a hexalobular internal by Camcar Textron, Torx is a registered trademark with some of the most commonly used fasteners used for a wide variety of applications. What is a Torx key? The Torx Plus, also known as the Internal Plus, is an improved version of the original design. This version is designed to provide better torque transfer than the original design. The lobes on the screw allow for increased torque without causing much wear on the tool. a b c U.S. Patent 3,584,667, Bernard F. Reiland, "Coupling arrangement and tools for same", filed 1967-03-21

Types of Torx keys and uses

The TORX(r) drive system has several benefits, including an easy solution to a common fastener problem, higher productivity, and enhanced reliability. You can also reduce total assembly costs by using the TORX(r) Drive System. SAE vs metric equivalents The metric system is more widely used in other countries. In the United States, the Imperial system is still used. It is based on the Roman Empire's system, which considered one foot to be the length of a human being. This means that the same tool in metric units won't fit an Imperial nut. Tamper-Resistant TORX PLUS Drive System" (PDF). Textron Fastening Systems. Archived from the original (PDF) on 2006-11-10. Construction Range Overview (Fasteners: Introducing the AW Drive System, p. 3)" (PDF). Würth New Zealand. 2016. The following is a Torx Bit Sizes Chart for Internal Torx. Two dimensions are important with respect to Torx screws. They are Point to Point and Diameter of the screw threads. Torx Size

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 Torx Paralobe is a further developed Torx Drive System with 6% longer Flanks which results in a 20% higher applicable torque. [15] Torx Plus [ edit ] Torx Plus head patternThe most common sizes of a Torx screw are T10, T15, and T25. There are also specialized Torx sizes, including T47, T55, T60, and T65. These are used in certain circumstances, but they are not as common as the T10, T15, and T25.
