M4 x 12mm Security Pin 5Lobe C-sunk Screw in A4 Stainless

These attractive 5-Lobe Pin security machine screws offer an improved tamper resistance compared to the more commonly available 6-Lobe Pin drive. The tooling is therefore more specialised and harder for members of the public to get hold of. Also known as torx plus or pentalobe screws, this variant has a countersunk head. Torx and other lobed designs allows for a higher torque to be exerted than a similarly sized conventional hex socket head.
