M4 x 25mm 5 Lobe Pin Button Security 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 button
head. Torx and other lobed drive designs allows for a higher torque to be exerted than a similarly sized
conventional hex socket head.
