Value Collection MPA98001 Wedge Lock Washer M10 Zinc Flake

Product Description

The VALUE COLLECTION MPA98001 is a wedge lock washer designed to maintain clamp load in bolted assemblies subject to vibration and dynamic loads. Built to an M10 thread size with a maximum outside diameter of 0.6535 inches and a maximum inside diameter of 0.4291 inches, this washer uses a wedge-face geometry to resist loosening under cyclic stress. The zinc flake finish provides corrosion resistance in typical indoor and light-duty outdoor fastener applications. Manufactured to Grade 2 material standards and conforming to ISO 9001 and ISO 14001 quality and environmental management certifications, it suits assembly technicians and maintenance trades working on mechanical equipment.

This wedge lock washer is suited for use in mechanical assemblies, industrial equipment, structural connections, and maintenance applications where conventional flat or split-lock washers are insufficient to prevent fastener back-out. Its M10 thread compatibility makes it a common fit for general-purpose bolted joint assemblies in manufacturing, HVAC equipment mounting, electrical panel hardware, and light structural work. Each package contains 25 washers, making it practical for bench stock or small-batch repairs.

Installation Notes

Installation is performed by qualified assembly technicians or maintenance trades using standard hand or power tools. Always de-energize or isolate the equipment being serviced before disassembling bolted joints. Install washer pairs with the serrated faces mating against each other and one smooth face against the bearing surface, following the wedge lock washer manufacturer assembly pattern. Do not reuse washers that show deformation, corrosion, or loss of surface coating.
