Shear Bolts

Shear bolts are a type of anti-theft bolt, used in many industries where robust permanent security fixings are required. A wide range is available from stock with specials made to order.

How shear bolts work

Shear bolts (or snap-off bolts) are a premium 1-way permanent security solution, ideal where maintenance is not required. The hexagonal shaped section on top of the bolt snaps off when fully tightened, leaving a tamper-proof dome, countersunk or cap head. Please click on the links below for detailed product information, size charts, drawings and technical specifications.


The hexagon shaped section is the ‘drive’ part of the shear bolt and can be installed using a standard spanner or socket tool. Once the force applied to tighten the shear bolt reaches the shear-off torque, the hexagon section and collar snaps off, leaving only the shear bolt head with no drive or means of removal.
Shear bolts provide a permanent security fixing, ideal for use in prisons, banks, automotive, MOD and aerospace etc.

A wide range of shear bolt types and sizes (including dome head, countersunk head and cap head shear bolts) are available from stock in A2 stainless steel and we can also manufacture to customer requirements and drawings in any material, diameter or length.
