Value Collection 42460 M4 Standard Flat Washer Steel Zinc-plated

Product Description

The VALUE COLLECTION 42460 is a metric M4 standard flat washer manufactured from steel with a zinc-plated finish. Designed to distribute clamp load and protect mating surfaces under M4 fastener heads and nuts, this washer measures 4.3mm inside diameter, 9mm outside diameter, and 0.8mm thick. It conforms to DIN 125, ISO 7089, and ISO 7090 fastener standards and carries a hardness rating of 140 HV. The zinc plating provides baseline corrosion resistance for general-purpose indoor and light outdoor applications. Installers across mechanical, electrical, and plumbing trades use this washer wherever an M4 screw or bolt requires a load-spreading bearing surface.

This washer is suited for light to medium-duty assembly work in residential and commercial applications. Typical use cases include equipment mounting, panel assembly, fixture attachment, and general hardware assembly where M4 metric fasteners are specified. Its compliance with DIN 125, ISO 7089, and ISO 7090 makes it appropriate for applications requiring standardized metric hardware. Sold individually, with a minimum order quantity of 200 pieces.

Installation Notes

Install between the fastener head or nut and the mating surface to distribute clamping load and reduce surface damage. Ensure the washer bore seats flush and concentric with the fastener shank before torquing. Zinc-plated washers are suitable for dry or mildly humid environments; consider stainless or galvanized hardware for prolonged moisture or outdoor exposure. Handle per applicable mechanical assembly codes for the trade and equipment type being serviced.
