Triangular raised safety 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 triangular raised safety bolt is a specialized fastener designed to provide enhanced security by deterring tampering or unauthorized removal. Here are its key characteristics:

Features:

1. Triangular Head Design:

   • The bolt has a three-lobed (triangular) raised head, requiring a matching triangular socket or driver for installation/removal.

   • Unlike standard hexagonal or Phillips heads, this shape makes it difficult to grip with common tools like wrenches or pliers.

2. Raised or Domed Profile:

   • The head is slightly raised or domed, preventing easy access to the edges with prying tools.

   • The smooth, curved surface makes it hard to grip with locking pliers or vice grips.

3. Tamper-Resistant:

   • The uncommon shape acts as a deterrent against casual tampering.

   • Often used in public fixtures, security panels, or high-theft-risk applications.

4. Material & Finish:

   • Typically made from hardened steel, stainless steel, or brass for durability.

   • May have corrosion-resistant coatings (e.g., zinc plating, black oxide) for outdoor use.

5. Thread Types:

   • Available in machine thread (bolts) ou self-tapping thread (screws) depending on application.

Common Uses:

• Security panels & enclosures

• Triangular raised safety bolt

• Public infrastructure (e.g., restroom fixtures, signage)

• Electronics & machinery requiring restricted access

• Transportation (e.g., license plates, rail components)
