Hexagon socket shear bolt

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 socket shear bolts, also known as shear head bolts or breakaway bolts, are specialized fasteners designed to provide tamper-resistant security. Here’s a detailed description:

Key Features:

Hexagon Socket (Allen Drive):
- The bolt has an internal hexagonal drive (Allen key socket) for installation.
- Once tightened to a specified torque, the head shears off, leaving only a smooth, non-grippable surface.
- Hexagon socket shear bolt
Shear Mechanism:
- The bolt head is designed to break away after installation, preventing removal with standard tools.
- The remaining shank is flush with the surface, making it difficult to tamper with.
Materials & Finishes:
- Typically made from high-strength steel, stainless steel, or alloy metals.
- Common finishes include zinc plating, black oxide, or corrosion-resistant coatings.
Tamper-Resistant Design:
- Used in applications where security and vandalism prevention are critical (e.g., public infrastructure, electrical panels, railway systems).
Common Applications:
- Security panels (traffic signals, utility meters)
- Aerospace & automotive assemblies
- Railway & construction (permanent fastening)
- Military & defense equipment
- Hexagon socket shear bolt

Types of Hex Socket Shear Bolts:

Standard Shear Bolts: Break at a pre-set torque.
Countersunk Shear Bolts: Sit flush with the surface after shearing.
Shoulder Shear Bolts: Have an unthreaded section for precise alignment.
