Pin Hex Countersunk Security Machine Screw Grade 10.9

Pin Hex Countersunk Security Screws Stock Sizes

Pin Hex Countersunk Head Security Machine Screws host a reduced head to fit flush in the screws target housing.

Designed to reduce cam-out, which can occur regularly in Phillips and 2-Hole Drives. This helps with lessening the risk of damaging the drive tip, screw head and also the application. The Hex drive also allows better torque compared to conventional screw heads.

They offer medium security and are ideal in applications where the fixing needs to be removed for maintenance, whilst providing a security resistance against vandals and thieves at a relatively low cost.

They can also be referred to as Hex Pin, Tamper Pin Hex, Socket Screw with Pin and Din 7991 with Pin.

Available in M3 to M12 as standard with specials available to order.
