Irwin 10504353 Torx T20 x 25mm Screwdriver Bits (10 Pieces)

Product Information

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. A smaller number corresponds to a smaller point-to-point dimension of the screw head (diameter of circle circumscribed on the cross-section of the tip of the screw driver). Standard Torx drivers can be used to drive Torx ttap screws, but Torx ttap drivers will not fit standard Torx screws.

The "external" variants of Torx head sizes (see below) are described using the capital letter "E" followed by a number ranging from E4 to E44. The diagram depicts the interaction between the male and female components of a conventional hex drive and a Torx drive.

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. p>

A version known as Security Torx, Tamper-Resistant Torx (often shortened to Torx TR) or pin-in Torx contains a post in the center of the head that prevents a standard Torx driver (or a straight screwdriver) from being inserted. The "E" numbers are different from the "T" numbers of the same size: for example, an E4 Torx socket fits a T20 head. Torx screws are commonly found on automobiles, motorcycles, bicycle brake systems ( disc brakes), hard disk drives, computer systems and consumer electronics.

It features a second recess to create a "stick-fit" engagement (branded Frixion Fit), designed to minimize wobbling (branded Stable Drive) without pressing and the need for magnetic bits, a feature that can be important to certain industrial users. 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. Standard Torx drivers can be used to drive Torx Plus screws, but not to full torque because of the loose fit. Late or missing payments may have serious consequences for you and cause you serious money problems.
