Cone Head Security Nuts Galvanised

Cone Head Security Nuts

Finish = Galvanised

Gauge / Size option: M8, M10, M12

Cone head security nuts, also known as security shear nuts, breakaway nuts, snap off nuts or permacone nuts.

Designed to prevent tampering or removal of the nut and bolt.

Ideal when used erecting security fencing or where there is a need for extra security.

Can be used anywhere where a permanent fixing is needed.

The hexagon nut section is fully tightened with a standard spanner or socket until the pressure applied surpasses the maximum torque limit, which causes the hexagonal part of the nut to break off, leaving a plain tamper resistant cone shape which is extremely difficult to remove as there is nothing to grip.
