S-91074A314 0.77" ID x 1.36" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through wedge-lock design that maintains tension under extreme dynamic loads
• Maximum locking security with dual-sided serrations that bite into both mating surfaces for enhanced grip
• Exceptional corrosion protection from zinc-flake coating that withstands harsh industrial environments
• Consistent performance ensured by Rockwell C46 hardness rating for reliable, long-term service life
• Precise M18 metric compatibility with 0.77" ID and 1.36" OD dimensions for perfect fit in industrial assemblies
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements
• Optimized load distribution through 0.120-0.140" thickness range that prevents surface damage and maintains joint integrity

Professional Applications & Engineering Value

This M18 wedge lock washer delivers critical vibration resistance in demanding industrial applications where fastener loosening can lead to equipment failure. The zinc-flake-coated steel construction provides superior corrosion protection while maintaining the structural integrity needed for heavy machinery, transportation equipment, and construction applications. The top and bottom serration design creates a mechanical locking action that bites into both the fastener and mating surface, effectively preventing rotational movement even under extreme vibration conditions. This dual-sided engagement system eliminates the need for additional locking mechanisms, reducing assembly time and maintenance costs while ensuring reliable performance in critical joints subject to dynamic loading and thermal cycling.

Specification Summary & Compliance

Manufactured to precise metric dimensions with 0.77" inner diameter and 1.36" outer diameter, this wedge lock washer features a controlled thickness range of 0.120-0.140" for consistent performance. The Rockwell C46 hardness ensures optimal strength and durability, while the zinc-flake coating provides enhanced corrosion resistance. This product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, making it suitable for global industrial applications requiring strict regulatory adherence.
