六角穴付シャーボルト

主な特徴
    • 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.

    • The bolt head is designed to break away after installation, preventing removal with standard tools.

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

主な特徴
  1. 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.

    • 六角穴付シャーボルト
  2. 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.

  3. Materials & Finishes:

    • Typically made from high-strength steel, stainless steel, or alloy metals.

    • Common finishes include zinc plating, black oxide, or corrosion-resistant coatings.

  4. Tamper-Resistant Design:

    • Used in applications where security and vandalism prevention are critical (e.g., public infrastructure, electrical panels, railway systems).

  5. 一般的な用途:

    • Security panels (traffic signals, utility meters)

    • Aerospace & automotive assemblies

    • Railway & construction (permanent fastening)

    • Military & defense equipment

    • 六角穴付シャーボルト
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.
