Application Summary AI generated

This standard specifies the dimensional allowances and thread profiles required on external screw threads to accommodate the thickness of a hot-dip galvanized coating. It is applied in mechanical and structural engineering, particularly for bolts, studs, and other threaded fasteners that undergo hot-dip galvanizing for corrosion protection. The standard ensures that after coating, the threads remain functional and can be assembled with corresponding internal threads without interference.
