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 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. 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

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. The Torx Plus Drive system was developed to improve assembly line performance. Alignment difficulties between drive bits and recesses can slow down production lines. The Torx Autosert feature guides the driver bit accurately into the recess creating a self-centering engagement action. 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 Here’s a summary of just some of the issues associated with various typical, commonly used drive systems. Hex DriveAs shown, Torx clearly outperforms other drive systems when considering factors of importance in production environments. But Torx is far from perfect which is what led to the development of Torx Plus. Fast Reliable Service... your goods will normally be delivered within 1 to 3 working days - call us if you need them urgently! Torx Plus is designed for high torque transmission. This means that higher torques can be used to securely tighten fasteners without incurring additional wear and tear on the tools. High torque capability is also very important in service situations where corrosion may increase the torque required to loosen a fastening. Tamper Resistant Torx Plus Drive

The drive systems used by various fasteners have a huge impact on productivity and product quality. For example, an inefficient drive system will increase assembly time and therefore eat into profitability. The design of the Torx Plus resembled that of a gear with more square lobes. This design change resulted in application of even greater torque on the head with minimum wear. The Torx screwdriver was invented by Camcar Textron in 1967. It is considered one of the most efficient fastening systems. The design has six points and a center pin. This design allows for more torque and minimizes wear.The metric system is a good fit for larger distances. It is not as accurate for smaller distances. Tamper-Proof 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. Tamper Proof Torx (Secure Torx) version of the “Plus” had only 5 Lobed instead of 6. These are not that popular.
