Metal Screws Fasteners During processing and processing, especially during the pickling and caustic washing before plating, and subsequent plating, the surface absorbs hydrogen atoms and the deposited metal coating traps hydrogen. When the fasteners are tightened, hydrogen is transferred toward the most concentrated part of the stress, causing the pressure to increase beyond the strength of the base metal and create a tiny surface crack. Hydrogen is particularly active and penetrates quickly into newly formed fractures.
The working life of a hardware screw fastener in a corrosive atmosphere is directly proportional to the thickness of its coating. The general recommended economical plating thickness is 0.00015 to 0.0005 in (4 to 12 um). Hot-dip galvanizing: The standard average thickness is 54 um (claim diameter ≤ 3/8 is 43 um), and the minimum thickness is 43 um (call diameter ≤ 3 /8 is 37um).
