Safety Wire Bolt electroplating yellow

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.

Here’s a structured overall description of safety wire bolts with yellow electroplating:

1. Definition & Purpose

• Safety Wire Bolts: Fasteners designed with holes or notches to allow the threading of safety wire, preventing loosening due to vibration or rotation.

• Yellow Electroplating: A surface treatment providing corrosion resistance, aesthetic appeal, and visibility (often for identification or safety marking).

2. Electroplating Process (Yellow)

• Base Material: Typically steel, stainless steel, or titanium.

• Plating Layer:

  • Undercoat: Often zinc or cadmium electroplating for corrosion resistance.

  • Topcoat: Yellow chromate conversion coating (for zinc) or yellow dye/paint (e.g., zinc-nickel alloy with yellow passivation).

• Standards: Compliant with ASTM B633 (zinc plating), MIL-DTL-45204 (cadmium), or AMS 2468 (yellow chromate).

• Safety Wire Bolt electroplating yellow

3. Key Features

• Resistência à corrosão: Yellow chromate layer enhances protection against rust.

• High Visibility: Bright yellow color aids quick inspection in machinery or aerospace applications.

• Durabilidade: Withstands harsh environments (e.g., automotive, marine, or aerospace).

4. Applications

• Aeroespacial: Engine components, landing gear.

• Automóvel: High-vibration areas (e.g., race cars, motorcycles).

• Máquinas industriais: Critical bolted joints subject to dynamic loads.

5. Safety Wire Compatibility

• Pre-drilled holes or wire grooves accommodate stainless steel safety wire (e.g., 0.032″ diameter).

• Wire wrapping follows ANSI/MSNAS standards to ensure secure locking.

• Safety Wire Bolt electroplating yellow

6. Advantages

• Resistência à vibração: Prevents bolt loosening.

• Chemical Protection: Electroplating shields against oxidation.

• Color Coding: Yellow may indicate specific torque or maintenance requirements.

7. Limitations

• Sensibilidade à temperatura: Some yellow dyes degrade at high temps (>250°C).

• Wear: Plating may wear off under friction; lubricants or additional coatings (e.g., PTFE) can help.

8. Compliance & Certifications

• ASTM/SAE: Standards for plating thickness/adhesion.

• RoHS/REACH: Compliance for hazardous substance restrictions.

9. Maintenance

• Regular inspections for plating wear or wire integrity.

• Avoid abrasive cleaners to preserve the yellow finish.

• Safety Wire Bolt electroplating yellow

10. Common Specifications

• Thread Standards: UNC/UNF, METRIC.

• Grades: Class 8.8, 10.9 (steel); A2/A4 (stainless).
