99.995% Zinc Plating Ball | Thin Uniform Coating Requirements for Fasteners Bolts and Nuts
Zinc balls are recorded with minimum 99.995% purity and 40–50HV hardness. Actual Zinc material is paired with a combined specification listing 25, 30, 40, 50 and 100mm.
Confirm the selected diameter and material acceptance through batch documents. Thin and uniform coating in the title requires a defined plating process and inspection target. The product size choice alone does not establish coating thickness or behavior on a fastener.
For bolts or nuts, provide substrate, bath and finish requirements. The source supplies no measured coating uniformity, corrosion or dissolution result. Request chemistry and dimensional inspection evidence before evaluation; general standard and purity labels do not guarantee anode performance or approve a finished coating for a particular service.
