Tianqi Fasteners offers a comprehensive range of Stainless Steel Spring Washers, engineered to provide superior locking power and tension control in demanding industrial assemblies. As an essential Spring Lock Washer, these helical split-ring components act as a powerful mechanical “spring” that provides constant axial tension. This active preload increases friction between fastener threads, effectively preventing the self-loosening of nuts and bolts caused by intense vibration, dynamic loads, and thermal expansion.
Our category includes specialized designs such as the JIS B 1251 Spring Washer, ANSI B18.21.1 Spring Washer, DIN 127 Spring Lock Washer, and GB93 Split Lock Washer. These products are manufactured with strict dimensional tolerances to ensure compatibility with metric and inch-based fasteners across industrial, marine, construction, and heavy machinery applications.
The helical split-ring design creates a vertical “bite” into the fastener head and mating surface. This active resistance provides a reliable locking mechanism that prevents hardware from backing out under heavy vibration or cyclic stress.
We manufacture to the world’s most recognized specifications, including DIN, ANSI/ASME, JIS, and GB. This ensures that our fasteners provide consistent dimensional accuracy and reliable performance for international projects.
Available in 304 and 316 for general corrosion resistance, and high-alloy grades like 2205 and 2507 (Duplex) for extreme environments. We also offer 321 for applications requiring high-temperature stability.
Our manufacturing process ensures high hardness and spring-back memory. These washers maintain their shape and spring tension even after repeated compression, resisting permanent deformation and ensuring a long service life.
Every Stainless Steel Spring Washer features standard concentricity and smooth, burr-free edges. This precision ensures a uniform load application, protecting mating surfaces from localized damage while providing a professional fit-and-finish.
