Safety Wire Bolt electroplating black

El proceso de estampado en frío es uno de los nuevos procesos de mecanizado a presión de menor o ningún corte
metal. Es un método de transformación que utiliza la deformación plástica del metal bajo la acción de
fuerzas externas y, con ayuda de moldes, redistribuye y transfiere el volumen de metal para formar
las piezas o formatos necesarios. El proceso de estampación en frío es el más adecuado para producir piezas estándar.
elementos de fijación como pernos, tornillos, tuercas, remaches, pasadores, etc.

Safety Wire Bolt Electroplating Black – Overall Description

1. Overview

A safety wire bolt (también conocido como lockwire bolt) is a specialized fastener designed to be secured with safety wire to prevent loosening due to vibration or movement. Electroplating black is a surface treatment applied to the bolt for corrosion resistance, aesthetic appeal, and improved durability.

2. Electroplating Black Process

• Material: Typically applied to steel, stainless steel, or other metals.

• Coating Type: Usually involves zinc electroplating with a black chromate conversion coating (Zn + Black Passivation).

• Process Steps:

  1. Cleaning & Degreasing – Removes oils and contaminants.

  2. Acid Pickling – Eliminates rust and scales.

  3. Electroplating (Zinc Coating) – Deposits a layer of zinc for corrosion resistance.

3. Key Features & Benefits

• Corrosion Resistance: Protects against rust and environmental exposure.

• Aesthetic Appeal: Provides a uniform, matte-black finish.

• Safety Wire Bolt electroplating black

• Durability: Extends bolt lifespan in harsh conditions (e.g., aerospace, automotive, marine).

• Electrical Conductivity: Maintains grounding capability (unlike some polymer coatings).

• Temperature Resistance: Suitable for moderate-high temperature applications.

4. Common Applications

• Aerospace: Engine components, landing gear, and critical fasteners.

• Military & Defense: Firearms, vehicle assemblies.

• Automotive & Racing: High-vibration environments.

• Industrial Machinery: Equipment requiring secure, vibration-resistant fastening.

• Safety Wire Bolt electroplating black

6. Considerations

• Compatibility: Must not interfere with torque or wire-locking function.

• Inspection: Coating should be uniform, free of peeling, and pass salt spray testing (e.g., 96+ hours ASTM B117).

Conclusion

A safety wire bolt with electroplated black finish combines mechanical security with enhanced corrosion protection, making it ideal for critical applications where reliability and longevity are essential.
