Description

~Fasteners is for fastening and widely application of mechanical parts are widely used all kinds of machinery, equipment, vehicles, ships, railways, Bridges, buildings, structures, tools, instruments, meters, and supplies such as above, you can see all kinds of fasteners.

 It is characteristic of various specifications, different performance purposes, and the degree of standardization, generalization is extremely high.

 So some called the existing national standards of fasteners, standard fasteners, or standard parts for short. A fastener is the most widely used mechanical components.

Fasteners including bolts, stud, screw, nut, washer, pin.

 Lock or killed often occurred in stainless steel, aluminum alloy and titanium alloy materials fasteners, the metal alloy is anti-corrosion performance, the surface damage, produce a thin layer of metal surface in the oxide layer to prevent further corrosion.

 When stainless steel fasteners are locking teeth lines between the pressure and heat will destroy the oxide layer, that occur between the metal thread blocking or shear, gelling of occur then.

 When this phenomenon continues, will make the stainless steel fasteners completely lock, lock cannot be removed or continue.
