Professional Applications & Engineering Value

This zinc-flake-coated steel wedge lock washer delivers critical vibration resistance in demanding applications where joint integrity is paramount. The top and bottom serration design creates a mechanical lock that bites into both the fastener head and base material, effectively preventing rotation and loosening caused by dynamic loads, thermal cycling, or machinery vibrations. Engineered with Rockwell C46 hardness, this heavy-duty washer maintains its structural integrity under high clamping forces while the corrosion-resistant zinc-flake coating protects against environmental degradation. Ideal for construction equipment, heavy machinery, transportation systems, and industrial assemblies, this wedge lock washer provides reliable performance where standard washers fail, reducing maintenance frequency and preventing costly downtime.

Specification Summary & Compliance

This washer features precise dimensional specifications with 0.67" inner diameter, 1.21" outer diameter, and thickness ranging from 0.120" to 0.140". Manufactured from high-strength steel with zinc-flake coating for superior corrosion protection, it maintains Rockwell C46 hardness for optimal performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide. Compatible with both 5/8" and M16 fastener systems, this wedge lock washer meets industrial standards for vibration-resistant fastening solutions.
