Hexagon socket shear bolts, also known as shear head bolts 或 breakaway bolts, are specialized fasteners designed to provide tamper-resistant security. Here’s a detailed description:
主要功能:
-
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).
-
-
常見應用:
-
Security panels (traffic signals, utility meters)
-
Aerospace & automotive assemblies
-
Railway & construction (permanent fastening)
-
Military & defense equipment

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.
