A shear nut is a type of fastener that is designed to be securely installed onto a bolt or screw, and then intentionally damaged or sheared off to prevent unauthorized removal or tampering.  The nut has a specialized shape, with a thinner section near the top of the nut that is designed to break away when sufficient force is applied.  This makes it difficult to remove the nut without specialized tools, providing a high level of security and resistance to tampering.  Shear nuts are commonly used in applications where security is a top priority, such as in industrial equipment, public infrastructure, and other critical installations.

What are they used for

Shear nuts are commonly used in high security applications where tampering or removal of fasteners is a concern. These nuts are designed with a specialized outer ring that shears off when tightened to a specific torque, leaving a conical-shaped nut that cannot be removed without cutting. Shear nuts are often used in public infrastructure projects, such as bridges and power stations, as well as in high security applications like cash safes and prison doors.

There are many shear nut manufacturers that specialize in producing high quality, tamper-resistant nuts for various applications. These manufacturers use advanced manufacturing techniques and materials to produce nuts that meet the rigorous safety and security standards required in these industries. Some of the leading shear nut manufacturers include NELSON STUD WELDING, TE-CO, and Superior Washer & Gasket Corp.

Manufacturing Process

The production process for shear nuts involves several steps. First, the raw material, typically steel or stainless steel, is shaped into the desired size and shape using a process such as forging or machining. Next, a specialized cutting tool is used to create the unique shear design on the nut, which allows it to break off when a certain amount of torque is reached during installation. The nuts are then heat treated to increase their strength and durability, and they may also be coated or plated with a protective finish. Finally, the finished nuts are inspected for quality and packaged for shipment to customers.
