Key Features & Benefits at a Glance
- Superior vibration resistance with dual-sided serrations that bite into mating surfaces, preventing loosening under extreme conditions
- Exceptional corrosion protection from zinc-flake coating, extending service life in harsh industrial environments
- Optimized dimensional compatibility with both inch (2") and metric (M52) screw systems, reducing inventory complexity
- Enhanced load distribution through precise 2.11" ID and 3.15" OD dimensions, minimizing surface damage
- Reliable mechanical performance maintained by Rockwell C46 hardness, ensuring consistent locking force
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for global supply chain integration
- Reduced maintenance frequency through durable steel construction and anti-loosening design
Professional Applications & Engineering Value
These wedge lock washers address critical vibration-induced failure points in heavy machinery, construction equipment, and transportation systems. The top and bottom serrations create micro-locking actions that resist rotational forces better than standard flat washers, while the zinc-flake-coated steel construction provides galvanic protection without hydrogen embrittlement risks. Engineers specify these industrial washers for bolted connections subject to dynamic loading, where traditional locking methods prove inadequate. The dual measurement system compatibility (2" screw size and M52) makes them ideal for multinational equipment manufacturers requiring standardized fastener security across different regional specifications.
Specification Summary & Compliance
Precision-engineered with ID 2.11" and OD 3.15" dimensions maintaining tight thickness tolerance (0.270-0.290"). Manufactured from hardened steel achieving Rockwell C46 hardness for consistent wedge lock performance. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The zinc-flake coating provides superior corrosion resistance compared to conventional plating methods.
