Product Description
Multi-Standard Stainless Steel Toothed Lock Washers
This comprehensive range of toothed lock washers complies with GB and DIN standards, featuring internal-tooth, internal serrated, external-tooth, external serrated, and conical serrated lock washers. Manufactured from 304 and 316 stainless steel, these washers provide excellent rust-proof and anti-corrosion properties, making them suitable for outdoor equipment, electrical machinery, cabinet assembly, and instrumentation applications.
The sharp peripheral teeth bite firmly into mating surfaces, significantly increasing friction and delivering reliable anti-loosening performance. Compared to standard spring washers, toothed lock washers offer superior performance under vibration conditions, making them ideal for thin sheet metal, castings, and other applications where slippage is a concern. Available in metric sizes ranging from M2.5 to M24, with conical serrated washers covering M3 to M16.
These washers serve as essential fastening components for mechanical manufacturing, electrical installations, and general industrial assembly applications.
