Outstanding anti-loosening performance - The internal tooth structure embeds at the bottom of the bolt head during tightening, forming a mechanical interlock locking, effectively resisting loosening caused by vibration and dynamic loads.
Advantages of stainless steel material - Made of 304/316 stainless steel, it has excellent corrosion resistance and oxidation resistance, suitable for harsh environments such as moisture, acid, and alkali.
Easy and efficient installation - No additional tools are required. It can achieve self-locking function when used in conjunction with standard bolts, significantly improving assembly efficiency.
Reusability - The elastic tooth plate structure allows for a certain number of assembly and disassembly cycles, reducing maintenance and replacement costs.

physical design:The inner ring has multiple teeth arranged radially, with the tooth shape inclined at a 45° angle. It forms multiple contact points with the bolt head for secure locking.

Material & Technics:High-quality stainless steel cold-rolled sheet, processed through precise stamping, deburring and polishing, with a smooth surface free of burrs.

mechanical property:The elastic modulus of the teeth is moderate, which can provide sufficient locking force without damaging the surface coating of the bolts.

Specification coverage:It is compatible with various metric bolt specifications ranging from M3 to M20, and the inner and outer diameter dimensions have accuracy in accordance with the GB/T 861.1 standard.

surface treatment:Original stainless steel luster, with the option of applying a passivation treatment to enhance corrosion resistance.
