Tamper Proof Nuts, also known as Security Nuts are nuts designed to be difficult (if not impossible) to remove or loosen without the proper tool, or in some cases at all. Generally speaking, tamper proof nuts are designed to be resistant to gripping devices such as pliers, vice grips or locking pliers. This shape is usually a tapered cone that can only be removed with a matching bit, or by chopping sections of the nut off to create a flat surface (most vandals are not going to do this).
This is why tamper proof nuts are commonly used in applications that are open to the public.
Tamper Proof Nut Kits are available in Tri Groove and Breakaway Shear nut varieties. Each nut has its own drive style and kits available include ratchets, sockets, and the nuts themselves.
