Zinc Coating

Zinc Coating

Have AQuestion

Zinc is a commonly used coating or plating for fasteners that offers excellent rust and corrosion resistance at a low cost. Like cadmium, zinc protects the substrate by providing a thin, protective barrier. The zinc is preferentially corroded when the coating is damaged or if the substrate is exposed to the environment from scratches or punctures. In this case, the zinc coating will always tarnish and corrode first while serving as a sacrificial coating to material it is protecting, such as steel.

Because zinc is a widely available material, one of the main benefits of zinc coated fasteners, including zinc-plated bolts, fasteners, and nuts, is that it is a cost-effective option. Compared to stainless steel fasteners, their zinc coated counterparts offer an acceptable level of strength and corrosion resistance for non-specialty applications at a cheaper price. In most cases, the level of corrosion resistance of is directly related to the thickness of the coating layer. Finally, zinc is a much more environmentally friendly option than cadmium.

Zinc coated fasteners, including zinc-plated bolts, screws, and nuts, are ideal for a wide range of industrial and outdoor applications. Zinc plating is typically used for screws and other small fasteners that will be exposed to corrosive conditions. Fasteners that have been zinc plated have a shiny, silvery or golden appearance, referred to as clear or yellow zinc respectively.

Zinc coated fasteners offer the following benefits and advantages:

  • Serves as a sacrificial coating for enhanced corrosion protection
  • Provides a protective barrier against moisture
  • Improved durability that increases the lifespan of the underlying metal
  • Low-cost option
  • Bright decorative finish with various surface appearances
  • Environmentally friendly plating or coating option
  • Flexible and ductile, which makes it able to contour to the shape of the substrate
  • Easy application with low-stress deposit that will not damage the substrate
  • Excellent adhesive properties and serves as an effective undercoat
  • Capable of being applied uniformly and evenly in large batches

    Just wanted to do a quick shout out and heartfelt thank you for getting [us] out of a bind and helping us fulfill an extremely large project for our largest customer. We got our parts machined, inspected, polished and assembled on time for delivery when we realized that we forgot the set screws that needed to be made from Alloy 20. I made several frantic calls trying to find these things and your company was the only one to answer me in a timely manner, answer all my questions about the set screws, and able to get the set screws rushed to us in order for us to make our promised delivery date. Our city made the fastest shrinking city in America due to oilfield slowdowns and coal industry shut downs. Other machine shops in our area are closing, and we able to stay open because we keep our delivery dates and quality standards and we can do that because of the vendors that we have come to rely on, such as U-Bolt-It. Thank you for keeping us going. Looking forward to having you fill upcoming orders.
