Hexagon 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.

Hexagonal Parafusos de cisalhamento – Description & Functionality

Hexagonal shear bolts are specialized fasteners designed for tamper-resistant and security-critical applications. They feature a unique breakaway design that prevents unauthorized removal once installed.

Caraterísticas principais

1. Hexagonal Head Design

   • Padrão 6-sided head for easy installation using a wrench or socket.

   • Made to shear off at a predetermined torque, leaving no gripping surface.

   • Hexagon shear bolt

2. Shear Mechanism

   • The head is engineered to break away once the bolt reaches its specified tightening torque.

   • After shearing, only a smooth, cylindrical shank remains, making removal difficult without specialized tools.

3. Threaded Shank & Tail

   • O protruding tail (excess length) may be cut flush for safety and aesthetics.

4. Material & Hardness

   • Typically made from hardened steel (grade 8.8, 10.9, or stainless steel).

   • Resists drilling, cutting, and tampering.

5. Security Benefits

   • Tamper-proof: No exposed head after installation.

   • Vandal-resistant: Difficult to remove without destructive methods.

   • Controlled installation: Ensures proper clamping force.

How Hexagonal Shear Bolts Work

1. Instalação

   • Inserted into a pre-drilled hole and tightened with a wrench.

   • At the precise torque, the hexagonal head snaps off.

2. Removal (If Required)

   • Requires special extraction tools (e.g., left-hand drill bits, bolt extractors).

   • Often necessitates drilling or grinding.

Aplicações comuns

• Traffic & infrastructure: Street signs, traffic lights, railway tracks.

• Public utilities: Electrical enclosures, meter boxes.

• Security systems: Bollards, fencing, access panels.

• Heavy machinery & automotive: Critical assemblies requiring tamper resistance.
