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

Product Information

Other tool manufacturers have been producing 8-, 10- and 12-point star drivers and sockets for many decades. The Torx design allows for a higher torque to be exerted than a similarly sized conventional hex socket head without damaging the head or the tool.

  Torx Plus Maxx Stems is a highly specialized variant used on the ends of fasteners opposite the bolt-head, and provides higher torque than other drive systems allow. 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. 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). p>

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. But some manufacturers and resellers head sizes are also abbreviated using "TX" or "Tx" in front of the number.

  The magnitude of this force is proportional to the cotangent of the angle (depicted in orange) between the green circle and the contact plane. p>

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 development of better torque-limiting automatic screwdrivers for use in factories allowed this change. 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.
