Value Collection FW5S003000-100BX M3 Flat Washer Zinc 100pk

Product Description

The VALUE COLLECTION FW5S003000-100BX is an M3 standard flat washer manufactured from steel with a zinc-plated finish. It follows DIN 125, ISO 7089, and ISO 7090 fastener standards, making it a reliable choice for metric fastener assemblies. The washer measures 3.2 mm inside diameter, 7 mm outside diameter, and 0.5 mm thick. It carries a hardness rating of 140 HV, providing consistent load distribution under a fastened joint. These washers are sold in minimum order quantities of 100 units and are suited for general mechanical assembly, maintenance, and fabrication work across multiple trades.

This washer is used wherever an M3 metric fastener requires a bearing surface to distribute clamping load and reduce the risk of surface damage or fastener pull-through. Typical applications include light mechanical assemblies, electrical panel work, HVAC equipment mounting, and general sheet-metal fabrication. The zinc-plated finish provides basic corrosion resistance suitable for indoor and protected outdoor environments. Installers working on commercial or residential mechanical systems will find this washer appropriate for low-load fastening tasks requiring a DIN 125 or ISO 7089-compliant component.

Installation Notes

Install using hand tools appropriate to the M3 fastener being used. Ensure the washer is seated flat against the mating surface before torquing the fastener. Power down or de-energize any electrical or mechanical system before performing fastener work on live equipment. Do not use zinc-plated washers in highly corrosive or submerged environments where a stainless or hot-dip galvanized finish would be more appropriate.
