Value Collection 125-5-Z-C M5 Flat Washer Steel Zinc-plated

Product Description

The VALUE COLLECTION 125-5-Z-C is a standard flat washer designed for use with M5 metric fasteners. It is manufactured from steel with a zinc-plated finish that provides basic corrosion resistance in general-purpose applications. The washer measures 5.3mm inside diameter, 10mm outside diameter, and 1mm thick. It meets DIN 125, ISO 7089, and ISO 7090 dimensional standards. Installers use flat washers like this to distribute clamp load across a fastened joint, protect the mating surface, and reduce the risk of fastener pull-through. This part is sold in a minimum order quantity of 100 pieces per order.

This washer is suited for light to medium-duty metric fastener assemblies across residential and commercial applications. Typical use cases include HVAC equipment panels, electrical enclosures, plumbing fixture brackets, and general mechanical assemblies where an M5 bolt or machine screw requires a standard bearing surface. The zinc-plated finish makes it appropriate for indoor and low-humidity environments. It is commonly installed by HVAC technicians, electricians, plumbers, and maintenance professionals working with metric hardware.

Installation Notes

Install with the appropriate M5 bolt or machine screw using standard hand tools. Ensure the mating surface is clean and free of debris before seating the washer. Power down or de-energize equipment before accessing fastened assemblies inside electrical or HVAC enclosures. Do not use zinc-plated washers in high-humidity, outdoor, or chemically aggressive environments where additional corrosion protection is required.
