1,Description:

The working principle of the shoulder screw mainly utilizes the interaction between the elastic groove on the screw and the elastic part of the nut to achieve the purpose of self-locking. Specifically, when the plug screw is tightened, the elastic part of the nut will be embedded in the elastic groove of the screw, generating frictional force and bite force, which keeps the nut firmly in place on the screw and makes it less likely to loosen. Meanwhile, the spring washer will also generate a certain elastic force, further increasing the locking force and preventing the nut from loosening. This self-locking mechanism enables the plug screw to maintain a good fastening effect even in harsh environments such as vibration and shock.

2,Applications:
Integral zinc plated low-carbon steel metric M6x20 captive bolt with yellow passivation zinc plating finish is economical universal limit fastener for industrial water pump oil pump and hydraulic pump batch manufacturing, optimized for medium-load indoor pump body assembly working conditions. Selecting high ductility low-carbon structural steel raw material, the whole bolt is integral hot-dip yellow zinc plating processed, the thickened yellow zinc passivation layer has excellent neutral atmospheric anti-rust ability, resist workshop oil mist, water vapor and industrial dust corrosion in pump production workshop, reduce daily storage rust risk of finished pump fasteners. Miniature M6x20 small-size captive structure adopts stamping forging integrated molding, compact overall structure, embedded hidden installation design will not occupy pump internal fluid flow space, specially used for fixing pump side end cover, sealing pressure plate, miniature motor connecting foot and pump cooling auxiliary sheet. Yellow zinc plating surface has obvious anti-rust identification color, convenient pump factory staff classify and distinguish fastener specifications during assembly, reduce installation mismatch error. Fine standard metric M6 thread has moderate hardness, not easy to damage cast iron pump body prefabricated thread holes during repeated maintenance disassembly, protect pump body base hole integrity, lower after-sales pump maintenance replacement cost. The bolt has low production cost, stable batch quality, meets general mechanical pump ISO assembly standards, suitable for circulating water pump, micro hydraulic pump, fuel transfer pump small parts fixed limit work. It can bear low-frequency vibration generated by pump rotor operation, built-in step limit avoids end cover offset gap, guarantee pump internal sealing performance, prevent liquid side leakage caused by loose fasteners. It supports automated assembly line feeding use, complete size standardization, no customized tolerance threshold, sufficient stock supply, cost-effective, is the mainstream anti-rust miniature captive bolt matched for civilian industrial pump manufacturing and assembly industry.

Available in small packing, carton packing, or pallet configurations to meet your shipping and storage requirements.
