Bolts and nuts

Bolts and nuts are usually protected against corrosion by applying a metal protective layer, for example. However, for special applications, the industry also requires special coatings to improve a specific property. One such application is internal hard silver plating of nuts. LGTB has developed a unique non-destructive process where the lead time for large quantities is significantly reduced and the quality of the precipitated layer is far above that of barrel-silvered items.

Production techniques

LGTB also offers silver coatings for large volumes in both drum and rack. In this process, the complete part is always coated.
