Shear Bolts Button Head

For use where no maintenance is required, shear snap-off bolts are a premium 1-way permanent security solution.

  • Tamper proof – permanent security fixing
  • Security bolt with unique shear off (snap-off) feature
  • Fastened using a standard socket or spanner
  • Button head secure bolt
  • Ideal for use in prisons, banks, automotive, MOD and aerospace

Button Head Shear Bolts, which are also known as breakaway or snap off bolts, are a premium one way security bolt. Shear Bolts with Countersunk head are also available.

These security bolts resemble a standard button head bolt with a hexagonal portion attached to the button head. They do not require a special tool and are fastened using a standard socket or spanner until the pressure applied exceeds the maximum torque limit on the bolt –  at which point the hexagonal portion ‘snaps off’, leaving a plain button head bolt with no drive available to remove it.

Shear bolts offer one of the best permanent security solutions available on the market and the nature of the bolt means that it is suitable for higher torque applications. It’s important to determine whether future maintenance will be required on your application in judging the suitability of shear bolts, as they are unable to removed once fastened.

Button Head Shear Bolts are often used in environments requiring high security such as prisons, banks, automotive, aerospace and Ministry of Defence.
