- Maximum locking security with dual-sided top and bottom serrations that bite into mating surfaces
- Exceptional durability from case hardening to Rockwell C51 hardness for long service life
- Versatile compatibility with both inch (No. 5) and metric (M3) screw systems
- Reliable performance in critical applications requiring consistent locking action
- Environmental compliance meeting RoHS 3 and REACH standards for global industrial use
Professional Applications & Engineering Value
This 316 stainless steel wedge lock washer delivers exceptional engineering value in applications where vibration-induced loosening compromises safety and performance. The dual serration technology on both top and bottom surfaces creates multiple biting points that resist rotational movement, making it ideal for industrial machinery, automotive assemblies, and marine equipment. The case hardened construction to Rockwell C51 ensures the serrations maintain their sharpness through repeated cycles, while the 316 stainless steel material provides superior corrosion resistance in chemically aggressive environments. This combination addresses the critical need for vibration-resistant fastening in high-stress applications where maintenance access is limited and failure is not an option.
Specification Summary & Compliance
This wedge lock washer features precise dimensions of 0.13" ID and 0.28" OD with thickness ranging 0.080-0.100", compatible with No. 5 and M3 screw sizes. Manufactured to exacting standards with case hardening treatment achieving Rockwell C51 hardness for optimal wear resistance. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
