Shear Nuts

Looking for a high security permanent fastener for your project? Shear nuts implement a tamper resistant cone that prevents passersby or those wishing to do harm from tampering with the fastener and creating a permanent fastening once fully tightened. Here at GSS Fasteners, we supply fasteners across the country and offer a range of stainless steel shear nuts for use in a variety of industry projects in the UK. If you would like to know more about how the shear system works or about other security fasteners we offer, please do not hesitate to get in touch with our team!

What is a Shear Nut?

Shear nuts are a great security fastener that makes it nearly impossible for a fixture to be tampered with after installation, and they get their name from the way that they are installed. No special tool is required for the installation and instead, each nut has a conical section that is topped by a threadless standard hex nut that shears off when predetermined torque exceeds a certain point on the nut.

The shear nut will ultimately resemble a trident nut or tri-grove and is frequently used in public places to reduce the risk of unwanted removal or tampering with outdoor fixings. They are manufactured to stand up to the outdoor elements and are easy to tighten or loosen pre-shearing with a spanner or wrench thanks to the hexagonal part of the nut itself.

Where are Shear Nuts Used?

When implemented properly, a shear nut leaves the options for damage and theft limited, which is why both the shear nut or shear bolt are used frequently in public areas to protect public property. For example, next time you’re sitting on a park bench, look down at the fastener used to keep the bench pinned to the ground, chances are the hexagon part you can see is the shear nut keeping it in place. In short, shear nuts can be found in a lot of different places to prevent the unauthorised removal of council or business property in public areas.

Frequently Asked Questions

What is a galvanised steel shear nut?

A galvanised steel shear nut is a type of security nut made from galvanised steel, known for its corrosion resistance. It features a standard hex socket design and is specifically engineered to shear or break away when excessive force or torque is applied.

What tools are required to install galvanised steel shear nuts?

To install galvanised steel shear nuts, you will typically need a standard hex socket wrench or a compatible tool. This allows you to securely tighten the nut in place, ensuring optimal security for your application.

Why are shear nuts ideal for security purposes?

Shear nuts are ideal for security purposes due to their unique design and material properties. They provide a strong deterrent against unauthorised removal, as the nut shears or breaks away when tampering is attempted. Additionally, the construction enhances durability and resistance to corrosion.

Can Shear nuts be removed?

While shear nuts are designed to resist removal without specialised tools, they can be removed if necessary. However, the process usually results in visible damage to the nut, indicating an attempted removal has occurred. This serves as a clear indication of tampering or unauthorised access.

What are the advantages of using shear nuts?

The main advantages of shear nuts include enhanced security, deterrence against theft or tampering, and visible evidence of any attempted removal. They provide a cost-effective solution to protect valuable assets and ensure the integrity of critical infrastructure.
