Plow Bolts - Available Finishes

South Coast Fasteners offers plow bolts in finishes that protect the fastener, extend working life, and keep your hardware performing under the grind of day-to-day use.

Yellow Zinc Cr+6

This finish adds a golden layer of corrosion resistance while giving the bolt a high-visibility look. Yellow zinc is commonly used on jobsite equipment, loaders, and outdoor gear where you want both protection and visibility for service and inspection.

Zinc Cr+3

A silver-toned plating that guards against rust while maintaining a clean appearance. Zinc Cr+3 is suited for general outdoor use, equipment builds, and machinery where both performance and professional presentation matter.
