Shear Snap Off Fasteners

Shear snap off fasteners are amongst the highest security permanent fasteners available on the market. They are fastened using a standard spanner or socket. On tightening, the hexagon portion snaps off leaving a plain head that cannot be removed. Shear screws and socket shear bolts work in a similar fashion but are fastened using their respective cross recess and Allen key drivers.

Shear nuts tend to be of the same, domed design whereas shear bolts are available as dome, countersunk, and cap heads with anchors also available.

Shear snap off fixings are suitable for environments where maintenance is not required and high security is essential, such as in vehicles, prisons and security fencing.
