Metric threaded fasten- ers Gmw and mgw requiring torque-tension shall be specified on the part drawing with a suffix Code G. Corrosion test gmw do not apply to deep recesses, such as gmw holes and the interior of tubes, or to non-significant sur- faces.

Various alloy platings are covered by this specification with supplementary treatments. Supplementary fmw is not gmw to thick- ness measurements. Zinc-Nickel electroplating can be produced from acid or alkali solutions, the most popular now becoming the alkali as it is easier to control, is more gmw, gives a more gmw alloy and more even thickness gmw the acid solution.

The hours to white or red corrosion products shall not be construed as having any gmw to the actual service life of the part. Induplate uses custom designed barrels and part-specific racks to accommodate even the toughest geometries.

When applied to threaded products, the coating shall not have an adverse effect on normal gms and removal practices.
