Stainless Steel Shear Bolts

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

Stainless steel shear bolts are specialized fasteners designed to break or “shear” at a predetermined torque or load, providing a controlled failure point in mechanical systems. Here’s a detailed description:

1. Material

• Made from stainless steel (typically grades like 304 or 316 for corrosion resistance).

• Offers high strength while resisting rust, chemicals, and extreme temperatures.

2. Design & Function

• Shear Feature: The bolt is engineered to snap at a specific shear load, protecting critical components from over-torque or mechanical failure.

• Head Design: Often features a breakaway head (e.g., hex, countersunk) that shears off once the desired torque is reached, leaving a smooth surface.

• Shank: May have a weakened section (necked down) to ensure consistent shear performance.

3. Applications

• Used in aerospace, automotive, marine, and structural engineering where controlled failure is necessary.

• Common in safety systems, shear pins, and tamper-proof assemblies.

• Stainless Steel Shear Bolts

4. Advantages

• Corrosion Resistance: Ideal for harsh environments (saltwater, chemicals).

• Precision Shearing: Ensures reliability in critical applications.

5. Standards & Specifications

• Complies with ASTM, ISO, or DIN standards depending on application.

• Available in various diameters, lengths, and shear strengths.

6. Installation

• Requires calibrated tools to ensure proper torque/shear point.

• Often used with locking nuts or washers for security.
