S-91074A138 1.1" ID x 1.54" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through the wedge lock design that maintains clamp load under extreme conditions
• Maximum locking performance with dual-sided serrations that bite into both mating surfaces
• Exceptional durability with Rockwell C46 hardness rating for long service life in demanding applications
• Enhanced corrosion protection through zinc-flake coating that withstands harsh industrial environments
• Precise dimensional compatibility with 1" screw sizes and inch system measurements for seamless integration
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global market acceptance
• Reliable performance in heavy-duty applications where consistent clamping force is critical

Professional Applications & Engineering Value

This zinc-flake-coated steel wedge lock washer addresses critical vibration-induced loosening challenges in industrial equipment and machinery. The top and bottom serrations create multiple locking points that dig into both the fastener and substrate, maintaining clamp load where standard washers fail. The Rockwell C46 hardness ensures the serrations remain sharp and effective through repeated stress cycles, while the zinc-flake coating provides superior corrosion resistance compared to conventional platings. Engineered for heavy-duty applications including construction equipment, agricultural machinery, and transportation systems, this washer delivers reliable performance where vibration resistance and long-term durability are paramount concerns for engineering teams.

Specification Summary & Compliance

This wedge lock washer features precise inch system dimensions with 1.1" ID and 1.54" OD, specifically designed for 1" screw sizes. The manufacturing maintains consistent thickness between 0.120-0.140" for reliable performance. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The zinc-flake-coated steel construction meets industrial standards for corrosion resistance and mechanical performance in demanding applications.
