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.

When using a screwdriver, the following points should be noted:
1. Select the appropriate specifications and materials of plug screws to ensure they are suitable for specific application scenarios and working conditions.
2. During the installation process, it is necessary to ensure the cleanliness and flatness of the nuts and screws to avoid impurities and burrs affecting the self-locking effect.
When tightening the plug screws, appropriate tools and equipment should be used to avoid over-tightening or under-tightening.
4. During use, regularly check the tightness of the plug screws. If any looseness is found, retighten them promptly.
5. When disassembling and replacing the plug screws, appropriate tools and methods should be used to avoid damaging the threads or spring washers, which may affect the re-use effect.

2,Applications:
High-gloss hard chrome plated carbon steel metric M3x10 ultra-small shoulder bolt is micro precision positioning fastener for steam turbine wind power turbine core accessory manufacturing, adopting full-surface thickened hard chrome plating process for high temperature anti-abrasion and steam corrosion resistance upgrading. Adopting refined high-purity carbon steel raw material with internal impurity removal smelting, the bolt undergoes precision grinding molding overall, ultra-small M3x10 miniature size is tailored for gap limit fastening of turbine blade auxiliary gasket, sensor fixed base, turbine heat insulation small baffle and flow guiding micro parts. High-hardness chrome plating surface reaches mirror smooth level, high temperature resistance up to 280 degrees centigrade, resistant to high-temperature water vapor erosion, tiny particle airflow abrasion and thermal oxidation faced by turbine internal components during equipment operation. Miniature integrated shoulder structure controls micron assembly gap, calibrate installation position of turbine precision sensing components, avoid data detection deviation caused by part offset, guarantee wind power and steam turbine operation monitoring accuracy. Fine pitch M3 metric thread is ground and rolled finely, tooth tip smooth burr-free, will not damage fragile turbine alloy base reserved holes, suitable for frequent debugging and disassembly of turbine detection accessories. Chrome plating layer has dense anti-permeability performance, isolate high-temperature steam molecule corrosion, prevent miniature bolt seizure and rust death after long-term static operation inside turbine sealed cabin, simplify later turbine overhaul disassembly work. Every micro bolt conducts full-size microscopic inspection and hardness screening, zero surface defect, stable mechanical performance under long-term airflow vibration, small installation load, will not affect dynamic balance of turbine rotating parts. It complies with power machinery turbine fastener inspection standards, batch size high consistency, exclusive for wind turbine generator, industrial steam turbine, energy power turbine precision accessory assembly and fixed positioning use.

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