[0002] Pins are a type of standardized fasteners that can be used for static fixed connections or for relative movement with the connected parts. They are mainly used at the hinges of two parts to form hinge connections. Pins are usually locked with cotter pins. They are reliable in operation and easy to disassemble. Pins need to undergo a quenching process during processing to enhance their comprehensive mechanical properties such as strength and toughness.
