Value Collection MPA98000 Wedge Lock Washer M6 Steel Zinc

Product Description

The VALUE COLLECTION MPA98000 is a wedge lock washer designed to prevent fastener loosening under vibration and dynamic loads. Built to M6 thread sizing, this washer features a camlock geometry that creates a secure wedge effect as the fastener is tightened, maintaining clamp load even when assemblies experience movement or thermal cycling. Constructed from Grade 2 steel with a zinc-plated zinc flake finish, it offers corrosion resistance suitable for general industrial and mechanical applications. The outside diameter measures 0.4331 inches maximum with a minimum of 0.4173 inches, and the inside diameter ranges from 0.2480 to 0.2638 inches.

This wedge lock washer is suited for mechanical assemblies, structural connections, and equipment maintenance where vibration-induced loosening is a concern. It is commonly installed in manufacturing machinery, industrial equipment, and general fabrication applications requiring a reliable anti-loosening solution. Each package contains 50 washers, making it practical for production use or service kit stocking. Installation is typically performed by maintenance technicians, millwrights, or assemblers working with M6 metric fastener systems.
