Value Collection CD557530 M8 Flat Washer Zinc-plated 100pk

Product Description

The VALUE COLLECTION CD557530 is a standard flat washer designed for use with M8 metric fasteners. Made from steel with a zinc-plated finish, it provides a load-bearing surface that distributes clamping force evenly across the joint. The washer measures 8.4mm inner diameter, 16mm outer diameter, and 1.6mm thick, conforming to DIN 125, ISO 7089, and ISO 7090 dimensional standards. Hardness is rated at 140 HV. This item ships in a package quantity of 100. Plumbers, HVAC technicians, electricians, and general mechanical contractors commonly use flat washers like this when fastening equipment panels, mounting brackets, and pipe supports.

This washer is suited for metric M8 bolt and screw applications in residential and commercial installations. Typical uses include equipment mounting, structural bracketing, and general mechanical assembly where a standard flat washer is required under a bolt head or nut to protect the mating surface and prevent fastener pull-through. The zinc-plated finish provides basic corrosion resistance in indoor and moderately exposed environments.
