Our spring lock washers are manufactured in strict compliance with ASME B18.21.1 standards, available in multiple types including regular, extra-duty, high collar, and heavy type helical spring lock washers. These washers are designed to compensate for developed looseness between component parts of an assembly while distributing the load over a larger area.
The washers are available in various materials including #70 steel, 65Mn steel, and stainless steel (18-8 or SS316) with multiple surface finish options such as black oxide, plain, zinc plating, yellow zinc, and hot-dip galvanized (HDG). Standard sizes range from #4 up to 3 inches, with 1/4" to 1" sizes typically kept in stock for immediate shipment.
Our spring lock washers meet various international standards including DIN127, DIN128 (metric) and GOST6402 (Russian standards). The washers are available with different hardness levels depending on material: carbon steel (38-46 HRC), stainless steel (35-43 HRC), aluminum alloy (75-97 HRB), and other specialty alloys.
We offer customized solutions for special requirements and can provide washers in various packaging options including cartons, pallets, or buckets. Our production facility maintains strict quality control to ensure all washers meet the specified dimensional tolerances and performance characteristics.
