Professional Applications & Engineering Value
This 316 stainless steel wedge lock washer addresses critical vibration-induced loosening challenges in industrial machinery, transportation equipment, and marine applications. The dual serration design on both top and bottom surfaces creates multiple biting points that resist rotational forces and maintain clamping force under extreme conditions. The case hardened construction to Rockwell C51 ensures the serrations maintain their sharpness through repeated cycles, while the 316 stainless steel material provides exceptional resistance to saltwater, chemicals, and industrial atmospheres. This combination makes it ideal for vibration-resistant fastening in critical assemblies where reliability cannot be compromised, from offshore platforms to food processing equipment requiring corrosion-resistant stainless steel fasteners.
Specification Summary & Compliance
This wedge lock washer features precise dimensions (ID: 0.17", OD: 0.3", Thickness: 0.080-0.100") compatible with both No. 8 inch and M4 metric screw sizes. Manufactured from 316 stainless steel and case hardened to Rockwell C51 for optimal performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications requiring reliable locking washers with superior corrosion resistance.
