PROLOK Kinmar Permanent Nut Galvanised

Max Security  ● ● ●

Kinmar Permanent security nuts are a unique patented high torque security drive system. A great alternative to the shear nut, leaving no unplated surface. The Kinmar Permanent nut can achieve an accurate and reliable torque rating and can be re-torqued if required. This is a permanent fixing as the nut can only be turned one way, providing the ultimate tamper proof option to match mating threads.
