Discover more about the Shear Nuts range.

Shear Nuts are a type of 1-Way Security Nut specially designed to prevent removal after installation. The hexagonal head of a Shear Nut is designed to snap off (or shear) after installation, leaving a permanent, tamper proof fastening. The installation breaking points for each Shear Nut can be found in the technical specification on the individual product pages.

Accu also lists Shear Bolts in our standard range, which can also be tightened with a spanner or wrench, with the head head of the bolt shearing off to leave a smooth permanent finish.

For an alternative type of tamper proof nut which can be re-tightened if needed and offers a superior high security solution, please see our range of Kinmar® Permanent Nuts.

Materials

Accu’s Shear Nuts are manufactured from a range of materials, including both A2 and A4 Stainless Steel as standard. A chemical matte black finish can also be applied to our Stainless Steel Shear Nuts.

Shear Nuts are also stocked in Mild Steel with either a Galvanised or a Bright Zinc Plated (Cr3) finish.

Sizes

Accu’s range of Shear Nuts are available in metric thread sizes M4 up to M24.

Tamper Proof Components

Accu also offers a full range of tamper proof Security Screws, which can be used alongside Shear Nuts for added security.
