Key Features & Benefits at a Glance
- Superior vibration resistance with dual-sided serrations that bite into mating surfaces to prevent loosening under dynamic loads
- Exceptional corrosion resistance thanks to Black-Oxide 316 Stainless Steel construction for harsh industrial environments
- Enhanced durability and wear resistance from case hardening to Rockwell C46 hardness
- Precise M8 metric compatibility with 0.34" ID and 0.65" OD dimensions for accurate fitment
- Reliable performance in extreme conditions with consistent 0.070-0.090" thickness maintaining clamping force
- Compliance with global environmental standards including RoHS 3 and REACH for international supply chain integration
- Double-sided locking action with top and bottom serrations providing twice the anti-rotation security
Professional Applications & Engineering Value
This M8 metric wedge lock washer delivers critical vibration-resistant fastening solutions for demanding industrial applications. Engineered with Black-Oxide 316 Stainless Steel, it provides superior corrosion resistance in marine, chemical processing, and outdoor environments where moisture and corrosive elements threaten fastener integrity. The dual-sided serration design creates multiple biting points that mechanically lock the fastener assembly, preventing rotational loosening caused by machinery vibrations, thermal cycling, and dynamic loading conditions. The case hardened construction to Rockwell C46 ensures the serrations maintain their sharpness through repeated installation cycles, offering reliable performance in heavy machinery, transportation equipment, and structural assemblies where safety-critical connections cannot compromise.
Specification Summary & Compliance
This wedge lock washer features precise metric dimensions with 0.34" ID (M8 screw compatibility) and 0.65" OD, maintaining consistent thickness between 0.070-0.090". Manufactured from 316 Stainless Steel with Black-Oxide surface treatment and case hardened to Rockwell C46 hardness. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets.
