Description

The fastener includes: bolts, screws, studs, nuts, washers, pin. Some metal alloys itself has corrosion resistance, the surface damage, in the surface of the metal to produce a thin layer of oxide layer to prevent further corrosion. When the stainless steel fastener is locked, the thread between the pressure and the heat would destroy the oxide layer, the metal screw thread occlusion or shearing, then adhesion phenomenon. When this phenomenon persists, will make the stainless steel fasteners locked, cannot remove or continue to lock on. Usually this a series of obstruction, shear, adhesion, locking a sequence of movements occur again within a few seconds, so a correct understanding of the use of this type of fasteners, to prevent this phenomenon.
