M4.2 (8G) x 32 mm Security Torx Self-Drilling Screw, 304 Stainless - YBDXA2M42X32

Made in 304 (A2) stainless steel, the Security Button Head Torx Self-Drilling Screw is a Torx security screw with a Torx recess that includes a centre pin, so it needs a matching security Torx bit to drive it. It has a drill point that drills its own hole in light steel..

A2 (304) stainless steel is the common general-purpose austenitic grade. It resists corrosion well indoors, in fresh water and in most general outdoor conditions, but it is not recommended where chlorides are present, such as coastal, pool and marine settings. Choose A4 (316) there. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread. Gauge sizes are shown as a number followed by G. On this range 6G is 3.5 mm, 8G is 4.2 mm, 10G is 4.8 mm, 12G is 5.5 mm and 14G is 6.3 mm, as listed by the supplier.

This listing has 4 variants covering sizes M4.2 (8G) to M4.8 (10G) and lengths 32 mm to 38 mm. Each variant is supplied in packs of 100.

Stainless threads can gall (seize) when tightened under load or at speed. A smear of anti-seize on the thread and a steady tightening speed reduce the risk.

Key specifications

Selecting the right option

A security screw only deters casual tampering. A matching security Torx bit is needed to fit or remove it. Check the variant for the bit size. The drilling capacity is not stated in the supplier data, so check it against the material thickness.
