Security Nuts

Tamper proof, tamper-resistant, or security nuts provide an added level of security for your project. These specialty nuts accomplish that task by requiring a special tool to remove the security nut. AFT currently offers a few different styles of removable and non-removable security nuts.

Types of Security Nuts

Tamperproof Spanner Nuts are removable security nuts that require a specialty spanner nut bit or complete spanner nut driver to remove. These non-ferrous rust resistant security nuts are made from zinc alloy and available in inch sizes 1/4-20, 5/16-18 and 3/8-16 along with metric sizes M6, M8 and M10.

Tamperproof Breakaway Nuts are non-removable security nuts where the hex nut will break away when the nut is tightened leaving only the tamper-resistant conical portion. Since this is a breakaway nut, no special tool is required and a standard wrench is only needed for installation.
