Stainless Steel Spring Washers
Product introduction
Stainless steel spring washers, crafted from premium austenitic stainless steel grades like 304 and 316, stand out as the top choice for anti-loosening in harsh conditions, including humidity, acid-base exposure, and high-salt environments. Formed via cold forming and precision heat treatment, these washers exhibit high-strength elasticity and excellent fatigue resistance. Their open-coil design generates continuous axial pressure after nut tightening, effectively countering loosening caused by vibrations and impacts, ensuring long-term stability of fastening systems. With inherent corrosion resistance, the surface remains smooth without additional anti-rust treatments, eliminating the risk of coating peeling. This makes them ideal for industries demanding high cleanliness and durability, such as food processing, medical equipment, marine engineering, and outdoor installations.
These products adhere strictly to international standards such as GB/T 93 and ISO 7093, available in a comprehensive range of sizes from M3 to M30 to fit various bolt specifications. 304 stainless steel washers balance cost-effectiveness and corrosion resistance for general anti-corrosion applications, while 316 stainless steel washers, enhanced with molybdenum, excel in chemical and marine environments. During installation, precise matching with bolts and nuts, along with tightening to standard torque values, is crucial for optimal anti-loosening performance. As a high-end anti-loosening solution, stainless steel spring washers offer long-lasting security for mechanical connections in challenging working conditions.
