4.2 mm x 19 mm Security Torx Self-Tapping Screw, 304 Stainless Steel - YBXTA28GX19
The price shown is for the pack.
Available
Made in 304 (A2) stainless steel, the Security Button Post Torx Self Tapping 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 self-tapping thread for thin sheet metal, plastics and timber..
You can choose from 16 variants, covering sizes 3.5 mm to 4.8 mm and lengths 13 mm to 50 mm. Each variant is supplied in packs of 100.
The A2 (304) stainless material suits indoor, fresh water and typical outdoor use. Where the fastening is exposed to salt air, pool chemicals or marine conditions, A4 (316) is the grade to use instead.
In wet conditions, keep stainless steel apart from aluminium and galvanised steel with a washer or sleeve, to reduce the risk of galvanic corrosion.

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. Drill a pilot hole and keep the driving speed low.
