Hexagon socket shear bolt

O processo de encabeçamento a frio é um dos novos processos para a maquinagem sob pressão com menos ou nenhum corte
metal. É um método de processamento que utiliza a deformação plástica do metal sob a ação de
forças externas e, com a ajuda de moldes, redistribui e transfere o volume de metal para formar
as peças ou os espaços em branco necessários. O processo de encabeçamento a frio é o mais adequado para a produção de
elementos de fixação, tais como cavilhas, parafusos, porcas, rebites, cavilhas, etc.

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

Caraterísticas principais:

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.

   • Hexagon socket shear bolt

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. Aplicações comuns:

   • 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.
