5-Lobe Torx - Countersunk Machine Screw - Stainless Steel (A4)
5-Lobe Torx Tamper Resistant (TorxTR) is a term commonly used to refer to 5-Lobe Torx. These 5-Lobe Torx Countersunk Machine screws are manufactured from A4 high tensile Stainless Steel and feature a special 5 Lobe Torx drive head.
5-Lobe Torx is an enhancement of the original Torx specification, designed to improve security and reduce wear and tear on both tooling and operators.
Developed as an alternative to the standard 6 lobe Resistorx countersunk security torx screw, this 5-Lobe Torx screw offers a higher level of security than the popular 6 lobe version, thanks to greater restriction on the availability of matching security driver tooling.
Manufactured from A4-70 stainless steel, which is a high tensile strength stainless steel, these machine screws offer excellent corrosion resistance, making them ideal for use in any indoor our outdoor application.
The countersunk head of this screw is designed so that when it is installed into a countersunk hole, the top of the screw will be flush with the surface of the substrate into which it has been installed.
