Zinc Plated
Understanding Zinc Plated Fasteners
Zinc plated fasteners provide an optimal balance of corrosion resistance and cost-effectiveness. This popular finish is applied through electroplating, creating a bright, uniform protective coating that shields the underlying metal from corrosion while maintaining precise thread tolerances. Our comprehensive selection includes zinc plated bolts, nuts, washers, screws, and anchors that meet or exceed industry standards.
As a trusted supplier of industrial fasteners, we offer both clear and yellow zinc plating options to suit various applications, from general construction to specialized industrial uses. Our zinc plated fasteners provide reliable performance with the added benefit of corrosion protection at an economical price point.
The Zinc Plating Process and Benefits
- Electroplating Process: Fasteners undergo a controlled electroplating process where zinc ions are deposited on the base metal, creating a uniform protective layer
- Corrosion Protection: The zinc coating acts as a sacrificial layer, protecting the base metal even if the surface is scratched
- Precise Tolerances: Unlike hot-dip galvanizing, zinc plating maintains tight thread tolerances essential for fastener performance
- Attractive Finish: Available in clear (silver) or yellow zinc options for enhanced aesthetic appeal
Applications and Usage Guidelines
Ideal Applications:
- Indoor construction and assembly
- Automotive components
- Machinery and equipment assembly

Frequently Asked Questions
What is the difference between zinc plated and hot-dip galvanized fasteners?Zinc plated fasteners have a thinner, more uniform coating (typically 5-15 microns) applied through electroplating, maintaining tight tolerances ideal for threaded fasteners. Hot-dip galvanized fasteners have a thicker coating (50-100 microns) offering superior corrosion resistance but may require oversized nuts due to coating thickness.
How long do zinc plated fasteners last?In indoor environments, zinc plated fasteners can last many years. However, their lifespan varies based on environmental conditions. For outdoor or harsh environments, hot-dip galvanized or stainless steel fasteners may be more appropriate for long-term applications.
Can zinc plated fasteners be used outdoors?While zinc plated fasteners offer some weather resistance, they are best suited for indoor or mild outdoor environments. For extended outdoor exposure or harsh conditions, consider hot-dip galvanized or stainless steel alternatives for better corrosion protection.
What's the difference between clear and yellow zinc plating?Clear zinc plating provides a bright, silver appearance while yellow zinc (also called gold zinc) includes an additional chromate conversion coating for enhanced corrosion resistance. Yellow zinc typically offers 2-5 times more corrosion protection than clear zinc.
