Discover more about the Torx Raised Countersunk Screws range.

AccuScrews’ Raised Hexalobular Countersunk Screws feature a Torx drive, also known as 6lobe, which prevents cam-out under high-torque operation. Raised Hexalobular Countersunk screws are intended for use with pre-drilled countersunk holes, and will sit flush with the target housing. The raised head of these components also gives them an aesthetically pleasing appearance. These components are designed for use with AccuScrews' Hexalobular Drive Bits.

In addition to A2 and A4 Stainless Steel, Torx Raised Countersunk Screws are available in a range of materials, including Aluminium, Brass, Phosphor Bronze and PEEK. All components within this range are precision rolled to achieve tolerances of ±0.13mm.

Thread-Locking and Finish Options.

Improve the longevity and stability of your Torx Raised Countersunk Screws with Accu’s pre-applied thread-locking patches. From the leading reliability of AccuLock Threadlocker to the heavy-duty Anu-Lok 180 and the high-performance Precote 80, your fasteners remain secure. Add a professional touch with AccuBlack chemical blackening, designed to minimise reflections and provide a premium aesthetic.
