Shear Nut - One Way A4 Security Nut - A4 Stainless Steel

A4 Stainless Steel Breakaway nuts are the latest addition to our Shear Nuts range. Suitable for both indoor or outdoor applications including use in harsh marine environments such as coastal locations.

A4 Stainless Steel is a Marine Grade Steel and a higher grade of stainless than standard A2, which is why its the recommended product for use in harsh environments such as coastal or other marine locations, or for use on-board boats and ships.

Shear nuts are also known as breakaway nuts, snap off nuts or permacone nuts. Once the nut has been tightened to a predetermined torque the hexagonal section breaks off, leaving the tightened conical section permanently in place.
