Shear Bolts

We understand the importance of good security whether you wish to protect a construction site associated with a recent project or safeguard a residential property and its contents. Our shear bolt range ensures the highest standard of security can be successfully achieved, whatever it is you wish to protect.

How do shear bolts work?

Shear bolts use the same principles as shear nuts to provide a quality, high security and permanent fastening. Once the shear bolt has been applied and subsequently tightened, the hexagon shaped part of the bolt breaks away to unveil a tamperproof head. There are numerous advantages that go hand-in-hand with the use of shear bolts. The one-way screw system makes the bolt particularly difficult to remove once it has been installed, whilst the one-off installation of this security bolt can be completed with a standard box, ring spanner or socket drive for added ease.

Often referred to as security breakaway or snap-off bolts, these security fixings provide a simple, efficient and economical option for those looking to deter vandals and thieves. Unlike the shear nut however, which once fixed may protrude, the shear bolt can be either countersunk or button style, for a more aesthetically pleasing finish that doesn't compromise on quality or performance.
