Stainless Steel Carbon Steel Spring Washer Spring Lock Washer

This type of spring washer (or spring lock washer) is a specialized anti-loosening fastening component designed for bolt connections. It is made of materials such as stainless steel and carbon steel, and has an overall structure of an elastic ring with an opening. Through the elastic deformation when the bolt is tightened, it provides continuous preload force for the connection pair, effectively preventing bolt loosening caused by vibration and impact. It is a fundamental and crucial anti-loosening component in industrial assembly.

Dual anti-loosening mechanism, secure and non-loosening

During the tightening process, the gasket is flattened, continuously releasing axial elastic force to counteract the attenuation of preload; at the same time, the sharp edges of the opening are embedded in the contact surface between the nut and the workpiece, significantly increasing the friction force. The dual protection completely eliminates the risk of loosening.

Multiple versions available, suitable for all scenarios

304 stainless steel model: Excellent corrosion and rust prevention performance, not prone to rust even in humid and outdoor environments for long-term use;

Galvanized (color zinc / white zinc) model: A cost-effective choice, with basic rust prevention ability, suitable for most conventional industrial scenarios;

Blackening model: High surface hardness, wear-resistant and scratch-resistant, suitable for heavy-load, oily, and high-frequency vibration working conditions.

National standard-level craftsmanship, precise dimensions for perfect fit

Strictly following GB/T 93 standards for production, the dimensional tolerance is controlled at the industry-leading level, perfectly matching the corresponding specification bolts and nuts, installing smoothly without sticking, and disassembling without hindrance.

High elasticity and anti-fatigue, durability at its peak

Selected high-quality spring steel / stainless steel materials, undergoing professional heat treatment process, repeatedly compressed without deformation or fracture, still maintaining stable elasticity under long-term high-frequency vibration, significantly reducing equipment maintenance costs.

Stainless steel version: Suitable for outdoor steel structures, water conservancy equipment, ship accessories, kitchen and bathroom appliances, etc. in humid or corrosive environments;

Galvanized version: Applicable to general mechanical equipment, building curtain walls, electrical equipment, automotive parts, etc. in common industrial scenarios;

Blackening version: Suitable for heavy-duty construction machinery, mining equipment, machine tools, heavy machinery, etc. in high-frequency vibration or oil-contaminated conditions;

All-inclusive general version: Suitable for all threaded connection scenarios in industries such as home appliance manufacturing, rail transit, wind power equipment, communication base stations, etc., where anti-loosening protection is required.

High corrosion resistance: 

The surface of the carbon steel galvanized spring gasket is treated with galvanization process, while the stainless steel spring gasket naturally possesses excellent corrosion resistance and is suitable for humid and chemical environments.

High strength: 

The carbon steel material ensures the stability of the product under high load, and the stainless steel material further enhances the durability of the product.
