Product description

After extracting the bolts and nuts from zinc tub, they are usually centrifuged to lose the redundant particles and then are heated by 300 degrees Celsius so that the layers of zinc and aluminum are very well baked on the surface. in order to have a highly resistant layer the entire process is repeated once more to form a firmly thick, low friction coefficient, blurry silver layer on top of the bolts and nuts.
