Hexagon head 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

Hexagon Head Shear Bolts are specialized fasteners designed to shear off at a predetermined torque, making them ideal for applications where over-tightening could damage components or where a specific breakaway force is desired. Here’s a detailed description:

Features:

1. Hexagon Head – Features a standard six-sided head for easy installation using a wrench or socket.

2. Shear Design – The shank is engineered with a weakened section (shear groove) that breaks off once the desired torque is reached, leaving a smooth, flush surface.

3. High-Strength Material – Typically made from hardened steel (grade 8.8, 10.9, or stainless steel) to ensure precise shearing under load.

4. Thread Type – Available in coarse (UNC) or fine (UNF) threads, depending on application requirements.

5. Corrosion Resistance – Often coated with zinc, galvanized, or other anti-rust treatments for durability in harsh environments.

6. Flange or Washer Option – Some variants include an integrated flange or washer to distribute load and prevent loosening.

Applications:

• Structural Engineering – Used in steel construction, bridges, and seismic bracing.

• Machinery & Automotive – Secures components that require controlled torque to prevent damage.

• Wind Turbines – Ensures bolts break away under extreme forces to protect critical parts.

• Military & Aerospace – Used in assemblies where precise failure points are critical.

Advantages:

• Prevents Over-Tightening – Shears off at a set torque, protecting sensitive components.

• Consistent Performance – Engineered to break at a precise load for reliability.

Common Sizes:

• Diameter: M6 to M24 (metric) or 1/4″ to 1″ (imperial).

• Length: Varies based on application (typically 20mm to 200mm).
