Hot-dip Galvanizing Process For DIN 603 Bolts

Due to the small size of DIN 603 bolts, irregular shapes and some threading, there are some obvious defects in hot dip galvanizing. It is difficult to screw the screw after plating. After the hot dip galvanizing, the residual zinc remains in the thread and is not easily removed, and the thickness of the zinc layer is uneven, which affects the fitting of the screw. It is stipulated in GB/T13912-199...
