Cr6 (Hexavalent Chromium) Plating Benefits

Maximum Protection in Harsh Environments

Cr6 plating is known for delivering some of the highest levels of corrosion resistance available for fasteners.

• Superior Corrosion Resistance: Excellent protection against moisture, chemicals, and harsh weather

• Enhanced Wear Resistance: Durable coating resists abrasion and surface damage

• Long Service Life: Extends fastener lifespan in outdoor and industrial settings

• Attractive Finish: Smooth, bright appearance with added protective value

Note: Cr6 plating is subject to increased environmental regulation due to toxicity concerns. It remains widely used where maximum corrosion protection is required.

Common Applications

G8 Hex Head Nuts with Cr6 plating are ideal for:

• Automotive and heavy truck assemblies

• Construction and structural fastening

• Industrial machinery and equipment

• Outdoor installations exposed to the elements
