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. Security Torx has its own set of variations, and many other variations of Torx drives are available in Security or TR versions. g. an E40 socket is too large to fit a T40 Torx bit, while an E8 Torx socket will fit a T40 Torx bit [6]).

No stripping or burring on the tip and the handle is shaped in a way where it’s comfortable and makes things easy to install or remove.To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. 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). The magnitude of this force is proportional to the cotangent of the angle (depicted in orange) between the green circle and the contact plane. 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.

Hexagonal drive screwdriver and torx bit is manufactured from the highest quality alloy steel • The screwdriver bit is 25mm in length and suitable for use with both hand and power tools • The HOT keys have (High Quattro Torsion) when tightening and l. An External Torx version exists, also known as Inverted Torx, where the screw head has the shape of a Torx screwdriver bit, and a Torx socket is used to drive it. Wera tough-absorbing (Z) bits prevent premature wear, making them suitable for use with hard materials. Because the plane of contact is not perpendicular to this circle, a radial force is also generated which tends to "burst" the female component and "crush" the male one.

But some manufacturers and resellers head sizes are also abbreviated using "TX" or "Tx" in front of the number. If this radial force component is too great for the material to withstand, it will cause the corners to be rounded off one or both components or will split the sides of the female part. A security Torx L-key and fastener with holes for a safety pin to hinder disassembly with an ordinary Torx key.
