Security Fasteners

Tamper-proof screws and nuts that need special drivers.

Overview

Security fasteners use drives such as pin-in-star, pin-in-hex and two-hole heads, plus shear nuts whose heads snap off once tight. They stop casual removal and theft.

We supply the matching drivers and bits with each order.
