Professional Applications & Engineering Value
These wedge lock washers deliver critical vibration-resistant performance in demanding industrial settings where fastener integrity is paramount. The Black Oxide 316 Stainless Steel construction provides exceptional corrosion resistance for applications exposed to moisture, chemicals, or outdoor elements. The top and bottom serrations create a mechanical locking action that maintains tension despite constant vibration, thermal cycling, or dynamic loading conditions. Engineered with case hardened treatment to Rockwell C46, these washers resist deformation under high clamping forces. Ideal for heavy machinery, transportation equipment, and industrial assembly lines, these anti-vibration washers prevent costly downtime by eliminating the need for frequent retorquing and maintenance interventions.
Specification Summary & Compliance
Precision manufactured to exacting dimensional standards with 0.21" internal diameter and 0.35" outer diameter, compatible with #10 inch and M5 metric screw sizes. Features controlled thickness between 0.080-0.100" for consistent performance. Manufactured using case hardening process achieving Rockwell C46 hardness for optimal strength and wear resistance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
