Security 6 Lobe Pin TX Socket Cap Captive Screws

Security 6 Lobe Pin TX Socket Cap Captive screws are medium security tamper-resistant fixings.

Captive screws are designed with an unthreaded portion below the head, referred to as the reduced shank. Once installed, this screw is meant to self retain, which prevents any loss of fasteners.

These screws are 2-way reusable fixings, suitable for higher torque applications and offer an economical solution for applications that require medium security and where the fixing may need to be removed for maintenance.

The 6-point star-shaped screw head with a centre pin will resist standard Torx bits, meaning they require a special insert bit or key wrench for insertion and removal.

Security 6 Lobe Pin TX Socket Cap Captive Screws are also referred to as Tamper Torx ®, Torx® Pin and Resistorx® and Star Pin Drive screws.

They are designed to reduce cam-out, which can occur in other drives such as 2-Hole and Phillips drives, reducing the risk of damaging the drive, screw head or the application. The drive also allows for improved torque when compared to more conventional screw heads.

Made of A4 Stainless Steel and Steel as standard, but other materials are available to order depending on your requirements.

Available in sizes from M2 to M10 as standard from Fastenright, while lengths range from 8mm to 100mm.

Non-standard sizes, materials and finishes are also available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
