Shear bolts black nickel plated

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.

Black nickel-plated shear bolts are specialized fasteners designed to provide both corrosion resistance and a controlled breaking point under specific torque or shear stress. Here’s a detailed description:

1. Material & Construction:

• Base Metal: Typically made from high-strength steel or alloy to ensure durability.

• Plating: Coated with black nickel, a dark, matte or semi-gloss finish that offers:

  • Corrosion Resistance: Protects against rust and environmental damage.

  • Aesthetic Appeal: Provides a sleek, non-reflective black finish.

  • Moderate Lubricity: Helps in tightening but is less slippery than zinc or chrome.

2. Shear Bolt Design:

• Purpose: Designed to shear off at a predetermined torque or load, acting as a mechanical fuse to protect machinery from overload damage.

• Weak Point: Often has a notched or reduced shank diameter to ensure controlled breaking.

• Shear bolts black nickel plated

• Aplicações comuns: Used in agricultural equipment (e.g., rotary cutters, augers), automotive safety systems, and industrial machinery.

3. Key Features:

• Controlled Failure: Prevents costly damage by shearing before excessive force harms other components.

• Thread Type: May have fine or coarse threads depending on application (e.g., metric or SAE standards).

• Head Styles: Hex head, flange head, or specialty heads for specific torque requirements.

4. Advantages of Black Nickel Plating:

• Enhanced Durability: More wear-resistant than plain or zinc-plated bolts.

• Decorative Finish: Often used in visible applications where aesthetics matter.

• Better Adhesion: Paint or coatings adhere better than to bright nickel.

5. Common Uses:

• Agriculture: Shear bolts in PTO shafts, mower decks, and harvesters.

• Automotive: Safety-critical shear points in seat belts or drivetrains.

• Industrial Machinery: Overload protection in conveyors or gearboxes.
