A zinc-plated stud is a metal fastener, typically made of steel, that has been coated with a layer of zinc to enhance its corrosion resistance. The zinc plating provides a protective barrier against rust and corrosion, making it ideal for use in environments exposed to moisture and other corrosive elements. Zinc-plated studs are commonly used in automotive, construction, and industrial applications.

Zinc-plated studs are widely used in various industries such as automotive, construction, aerospace, and manufacturing. They are used for fastening parts together, such as in car engines, building structures, machinery, and electrical systems. The plating also makes them suitable for outdoor or marine environments where moisture can cause rust.

Zinc plating typically involves electroplating the zinc coating onto the stud, which results in a thin, smooth layer. In contrast, hot-dip galvanizing involves dipping the stud into molten zinc, creating a thicker, more robust coating. Hot-dip galvanizing offers superior corrosion resistance for more extreme environments, but zinc-plated studs are sufficient for light to moderate exposure.
