M5 Shear Nut in A2 Stainless

Shear nuts are a permanent high security fastener that do not require specialist tooling to fit. They consist of a threaded cone section with a hexagonal head at the top. The hexagonal unthreaded part of the nut is designed to shear off as it is tightened at a pre-determined torque setting. This leaves behind the tamper proof cone which is very difficult to remove as there is no drive or grip. Great for uses where a permanent anti-vandal fixing is needed and used in schools and hospitals as well as the fencing industry and car industry.
