Pin TX Security Grub Screw (DIN 916 with Pin)

Pin TX Security Grub Screws, created to DIN 916 standard (ISO 4029) with a pin, are tamper-resistant fixings that require special driver bits or keys to fix or remove which means more conventional driver bits or Allen keys are useless.

These tamper-proof set screws are suitable for higher torque applications and the Pin TX drive makes it ideal for situations requiring medium security and where the fixing may need to be removed for maintenance.

They provide a range of advantages, one of which is that they are designed to reduce cam-out – which often occurs in Phillips and 2-Hole Drives. This aids in providing less risk of damaging the drive tip, screw head, or application, and the TX drive also allows for better torque compared to conventional screw heads.

These security grub screws, which provide a medium security resistance for a relatively low cost, can be referred to under a range of different names including TX Pin Grub Screws.

Available from Fastenright in a range of sizes and thread types, both Metric and Imperial. 6 Lobe Pin TX Drill Bit is also available from Fastenright.

Non-standard sizes and materials are available to order as specials, including custom parts made to drawings.Pin TX Grub Screw Technical Drawing
