Cup head 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.

Cup Head Safety Wire Bolts are specialized fasteners designed to secure components in high-vibration or critical applications where loosening could lead to mechanical failure. Here’s a detailed description:

Features:

1. Cup Head Design – The bolt has a rounded, domed head (similar to a button head but with a deeper cup shape) that provides a smooth, low-profile finish while allowing for secure wire attachment.

2. Safety Wire Holes – The head typically has two small, diametrically opposed holes drilled through it, enabling the threading of safety wire to lock the bolt in place.

3. Material – Often made from high-strength materials like stainless steel (e.g., AISI 304, 316) ou alloy steel (e.g., Grade 8, Inconel) for corrosion resistance and durability.

4. Tipo de rosca – May feature fine or coarse threads depending on the application (e.g., ANSI, metric, or aerospace standards).

5. Finishes – Common finishes include passivated, zinc-plated, or anodized coatings to prevent rust and wear.

Aplicações:

• Aeroespacial – Used in aircraft engines and control systems to prevent bolt loosening from vibrations.

• Motorsports – Secures critical components in race cars and motorcycles.

• Military/Defense – Ensures reliability in weapon systems and heavy machinery.

• Máquinas industriais – Locks bolts in high-vibration environments like turbines and pumps.

Safety Wiring Method:

• A stainless steel wire is threaded through the holes in adjacent bolts and twisted tightly, creating a loop that prevents rotation and loosening.

• Cup head safety wire bolt

Standards:

• Complies with MS, NAS, or AN specifications (common in aerospace).

• May also meet MIL-SPEC requirements for military applications.
