S-91074A150 1.47" ID x 2.17" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through dual-sided serrations that bite into mating surfaces, preventing loosening under extreme conditions
• Maximum clamping force maintenance with wedge lock design that increases tension as vibration attempts to loosen the connection
• Enhanced corrosion protection with zinc-flake coating that provides superior barrier protection in harsh industrial environments
• Exceptional durability with Rockwell C46 hardness rating ensuring long-term performance without deformation
• Dual measurement compatibility designed for both inch (1 3/8") and metric (M36) screw systems, increasing application versatility
• Reliable regulatory compliance meeting RoHS 3 and REACH standards for global industrial use
• Precise dimensional fit with 1.47" ID and 2.17" OD ensuring proper installation and optimal performance

Professional Applications & Engineering Value

Engineered for demanding industrial applications where vibration-induced fastener failure poses significant safety and maintenance concerns, these zinc-flake-coated steel wedge lock washers deliver exceptional locking performance through their unique dual-serration design. The top and bottom serrations create multiple biting edges that dig into both the fastener and mounting surface, creating a mechanical lock that actually tightens under vibrational stress. This wedge lock system is particularly valuable in heavy machinery, construction equipment, transportation systems, and manufacturing facilities where constant motion and impact would cause conventional washers to fail. The Rockwell C46 hardness ensures the serrations maintain their bite without wearing down, while the corrosion-resistant zinc-flake coating protects against environmental degradation in outdoor or chemically aggressive settings.

Specification Summary & Compliance

This heavy-duty wedge lock washer features precise dimensions with 1.47" inner diameter and 2.17" outer diameter, with thickness maintained between 0.250-0.270" for consistent performance. Manufactured from high-strength steel with dual-sided serrations on both top and bottom surfaces, the washer achieves Rockwell C46 hardness for exceptional durability. The product is fully compliant with RoHS 3 (2015/863/EU) regulations and meets REACH (EC 1907/2006) requirements, including the latest SVHC updates, ensuring environmental and safety standards are maintained for global industrial distribution and use.
