M4 Pin 5 Lobe Countersunk Security Screws in A4 Stainless Steel
            
            
	      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.
