Shear Nuts

Shear Nuts

This range of permafix security nuts are designed to be easy to install but to prevent nuts or bolts from being easily undone.
 
The Shear Nut is a one way type nut fixing, where the drive flange which allows the nut to be tightened, shears off once the nut is fully installed, leaving a threaded conical collar holding the secured item in place
