Security screws and the bits to drive them
The Security / Tamper-Resistant Screw page covers button and countersunk heads on machine and self-tapping threads, in 304 stainless, with drives a standard tool cannot turn: pin Torx, pin hex, one-way and snake-eye. The Barrel Nut Button Post Torx replaces a nut in timber and steel connections with a tamper-proof head.
Order the matching driver at the same time: Security Driver Bits & Keys, Bit Socket Post Torx and Bit Socket Post Hex. To protect an ordinary hex head bolt instead, a Secure Ring sits over the head and stops removal with standard tools.
