Safety Wire Bolt Electroplating Blue

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

Safety Wire Bolt Electroplating Blue – Overall Description

A Safety Wire Bolt Electroplating Blue is a specialized fastener designed for high-security applications where vibration resistance and tamper-proofing are critical. The blue electroplated coating provides corrosion resistance, visual identification, and enhanced durability.

1. Key Features:

• Electroplated Blue Finish: Achieved through zinc plating with blue chromate conversion coating or other passivation treatments.

• Safety Wire Holes: Pre-drilled holes (usually in the bolt head) to allow for locking wire (safety wire) installation, preventing loosening under vibration.

• High-Strength Material: Typically made from stainless steel, alloy steel, or titanium for demanding applications.

2. Purpose of the Blue Electroplating:

• Visual Identification: The blue color helps quickly distinguish safety-critical bolts in aerospace, motorsports, and industrial machinery.

• Corrosion Protection: Extends the bolt’s lifespan in humid, salty, or chemically aggressive environments.

• Wear Resistance: The electroplated layer reduces friction and galling during installation.

3. Common Applications:

• Aerospace & Aviation: Used in engines, landing gear, and control surfaces where bolts must remain secure under extreme vibration.

• Military & Defense Equipment: Ensures reliability in harsh conditions.

6. Limitations:

• Coating Wear: The blue finish may degrade under extreme friction or high temperatures.

• Special Installation Required: Proper safety wiring technique is needed for effectiveness.

Conclusion:

The Safety Wire Bolt Electroplating Blue is a high-reliability fastener designed for critical applications where vibration loosening is a risk. The blue electroplating enhances corrosion resistance and visibility, while the safety wire holes ensure long-term security.
