S-91074A135 0.67" ID x 1" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance prevents loosening under extreme dynamic loads, ensuring long-term joint integrity
• Dual top and bottom serrations provide maximum bite and anti-rotation performance on both contact surfaces
• Zinc-flake-coated steel construction offers excellent corrosion protection for harsh industrial environments
• Rockwell C46 hardness rating maintains structural integrity and prevents deformation under high clamp loads
• Dual measurement compatibility (5/8" and M16) provides flexibility for both inch and metric fastener systems
• Precision dimensional control with 0.67" ID and 1" OD ensures proper fit and optimal load distribution
• Environmental compliance ready with RoHS 3 and REACH certification for global industrial applications

Professional Applications & Engineering Value

This wedge lock washer delivers critical engineering solutions where vibration-induced loosening compromises safety and performance. The zinc-flake-coated steel construction provides superior corrosion resistance in demanding environments like heavy machinery, transportation equipment, and structural assemblies. The innovative dual serration design on both top and bottom surfaces creates multiple biting edges that resist rotational forces more effectively than single-sided alternatives. This makes the M16/5/8" compatible washer ideal for high-vibration applications in construction, manufacturing, and automotive industries where maintaining bolt preload is essential. The combination of Rockwell C46 hardness and precise dimensional tolerances ensures consistent performance in critical joints subject to dynamic loading conditions.

Specification Summary & Compliance

Manufactured to precise dimensional specifications with 0.67" inner diameter, 1" outer diameter, and 0.120-0.140" thickness range. Compatible with both 5/8" and M16 fastener systems, providing flexibility across measurement standards. The zinc-flake coating delivers exceptional corrosion protection while maintaining the structural integrity of the base steel material. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial applications requiring verified material safety and restricted substance control.
