Shear nuts are a well-established permanent security nut. They are driven with a spanner or socket and the hexagonal part shears off at a pre-determined torque, leaving a tamper-proof cone. Please bear in mind that a small amount of bare metal will be exposed at the shear point. In stainless shear nuts, this is not a problem, as a protective chromium oxide layer quickly forms, but for BZP and galvanised, you may wish to touch-up the nut with a spray of corrosion protection spray paint.
