M4 5-Lobe Pin Button Head Machine Screws - A4 ST ST
The 5-Lobe Pin security drive offers an improved tamper resistance compared to the more commonly available 6-Lobe Pin drive; as the tooling is more specialised and as a result harder for members of the general public to get hold of. We stock these in A4-70 Stainless Steel and have them available in Button Head and Countersunk in both self tappers and machine screws.
