Parts finished to the GMW clear specification are semi-bright silver gmw color. When applied to threaded products, the coating shall not have an adverse effect on normal gms and removal practices. Full production is run across 3 shifts and capacity is added to meet customer demand.

These fasteners shall be subject to torque-tension testing monitoring through the use of gmw M10 x 1. Only sources listed in the GM Materials File i. Gmw is an industry leader in supplying Zinc, Gmw Iron and Zinc Nickel plating for high volume automotive and safety critical components. Corrosion test gmw do not apply to deep recesses, such as gmw holes and the interior of tubes, or to non-significant sur- faces.
