Pin Hex Countersunk Self Tapping Security Screw

Pin Hex Countersunk Security Self Tapping Security Screws Stock Sizes

Countersunk Pin Hex Self Tapping Security Screws are available in A2 and A4 stainless steel and offer a medium security resistance against vandals and thieves at a relatively low cost.

Tamper-resistant, they require special driver bits or keys to fix or remove, making them an ideal fastener choice for applications where the fixing may need to be removed for maintenance.

They are designed to reduce cam-out, which often occurs in Phillips and 2-Hole Drives, and provide better torque compared to more conventional screw heads. This reduces the risk of damaging the drive tip, screw head or the application.

Their countersunk head allows the screw to sit flush in their housing hole, providing an aesthetically pleasing finish.

Otherwise referred to as Hex Pin, Tamper Pin Hex or Socket Screw with Pin, these fasteners are also available in non-standard sizes and materials as specials.

Please contact us with your requirements to further your enquiry.
