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.

Due to the high reliability and anti-loosening features of the plug screw, it is widely used in the following situations:
1. Mechanical equipment: such as CNC machine tools, plastic machines, presses, etc., require high-precision and highly reliable fastening parts.
2. Automotive industry: A large number of anti-loosening fasteners are needed in the assembly and maintenance of automotive parts, and plug screws are widely used in this field.
3. Rail Transit: In the assembly and maintenance of rail transit tools such as trains and subways, a large number of anti-loosening fasteners are also required. Plug screws have excellent performance in this field.
4. Aerospace: Plug screws are widely used in the structural fastening and maintenance of aircraft, rockets and other aircraft to ensure safety and reliability.

2,Applications:
Integral black oxide treated carbon steel socket step bolt in metric M5x16 micro specification is precision miniature fastener dedicated to automobile gearbox and industrial reduction gearbox internal assembly, adopting high-temperature steam blackening oxidation process for overall surface anti-rust treatment. Made of medium carbon carbon steel after integral tempering treatment, the bolt has matched hardness with gearbox internal gear accessories, moderate impact resistance, no hard scratch damage to alloy gear surface during contact operation. Inner hexagonal socket driving structure adopts deepened groove design, fits professional gearbox maintenance inner hex tool, convenient narrow-space hidden installation inside closed gearbox cavity, solves the problem of difficult fastening of outer head bolts in compact gearbox structure. Micro M5x16 small step structure achieves precise gap limit between gear spacer, bearing baffle and gearbox shell, control gear axial movement amplitude, reduce gear meshing friction deviation, improve gear transmission operation smoothness. Whole surface chemical black oxide film infiltrates metal surface texture, no coating peeling or falling off, can adsorb gearbox lubricating oil to form self-lubricating protective layer, reduce bolt surface dry friction wear, adapt long-term oil immersion working environment inside sealed gearbox. Different from plating coating, black oxide treatment will not produce coating impurity falling into gear oil, avoid gear tooth abrasion caused by impurity particles, protect internal gear precision parts. Products pass lubricating oil immersion fatigue test, stable limit performance under gear high-speed meshing vibration, small installation volume, high assembly density, applicable for automobile transmission gearbox, planetary reduction gearbox, miniature servo gearbox internal positioning assembly. It has low residual stress after processing, no later deformation, unified miniature tolerance, high assembly matching rate, is impurity-free self-lubricating dedicated step bolt for high-precision gearbox manufacturing industry.

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