Security Screws

Security screws use tamper-resistant drive styles that require special bits to install or remove, deterring vandalism and unauthorized disassembly. They protect public fixtures, electronics, equipment panels, and anywhere tampering is a concern. We stock security screws across the common tamper-resistant drive types, head styles, and materials.

Tamper-Resistant Drive Types

Pin-in-hex: a hex socket with a center pin that blocks a standard Allen key. Pin-in-6-lobe (pin-in-Torx): a six-lobe recess with a center pin — strong and common. Spanner (snake-eye): two round holes requiring a forked bit. One-way: slotted head that drives in but resists removal. Each needs its matching security bit.

Choosing a Security Level

One-way screws offer basic deterrence (install-only). Spanner drives resist common tools. Pin-in-hex and pin-in-6-lobe provide higher resistance and allow intentional removal with the correct bit — the best choice where authorized service is needed. The rarer the bit, the higher the security.

Materials and Finishes

Steel with zinc or black finish for general use, and 18-8 / 316 stainless for outdoor and corrosive environments — important since many security applications are exterior (signage, fixtures, transit).

Selecting the Right Security Screw

Choose the drive by required security level and whether authorized removal is needed — one-way for permanent, pin-in-6-lobe or pin-in-hex for serviceable security. Match head style to your countersink, and material to the environment. Stock the matching security bits, since standard drivers won't work. For maximum deterrence, choose a less common drive type.

Use the filters to narrow by size, drive type, head style, and material.
