Hexagonal safety wire 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.

A Hexagon Safety Wire Bolt is a specialized fastener designed to remain secure in high-vibration or high-torque environments, commonly used in aerospace, automotive, and industrial applications. Here’s a detailed description:

Caraterísticas principais:

1. Hexagon Head – Features a standard six-sided (hex) head for easy tightening and loosening with a wrench or socket.

2. Safety Wire Holes – Includes pre-drilled holes (usually two) in the head or shank to allow safety wire (lock wire) to be threaded through, preventing loosening due to vibration.

3. Material – Typically made from high-strength materials like:

   • Aço inoxidável (e.g., AISI 304, 316) for corrosion resistance.

   • Alloy Steel (e.g., Grade 8, 10.9) for high tensile strength.

   • Titanium (e.g., Grade 5) for lightweight, high-strength applications.

4. Tipo de rosca – May have fine or coarse threads depending on the application (e.g., metric or SAE).

5. Surface Finish – Often coated with corrosion-resistant treatments like zinc plating, cadmium, or anodizing (for aluminum variants).

Aplicações comuns:

• Aircraft & Aerospace – Securing critical components like engine parts, landing gear, and control surfaces.

• Motorsports – Used in engines, exhaust systems, and suspension to prevent bolt failure.

• Military & Defense – Ensures reliability in firearms, vehicles, and machinery.

• Máquinas industriais – Prevents loosening in vibrating equipment like turbines and pumps.

Safety Wire Method:

• The bolt is tightened to the correct torque, and then a stainless steel wire is threaded through the holes and twisted tightly, connecting it to another secured bolt or fixed point. This prevents rotation in either direction.

Vantagens:

• Resistência à vibração – Prevents self-loosening in dynamic environments.

• Fiabilidade – Provides a fail-safe mechanical lock where threadlockers may fail.

• Reusable – Unlike chemical adhesives, safety wire can be replaced.
