Value Collection 65119950-100 M5 Fender Washer 18-8 Ss

Product Description

The VALUE COLLECTION 65119950-100 is an M5 fender flat washer manufactured from 18-8 stainless steel with a plain finish. Fender washers are characterized by a larger-than-standard outside diameter relative to the inside diameter, which distributes clamping load over a wider surface area and reduces pull-through in thin or soft substrates. This washer carries a 5.3mm inside diameter and a 15mm outside diameter, conforming to DIN 9021. It is suited for use in plumbing, electrical, HVAC panel assembly, and general mechanical fastening applications where corrosion resistance and load distribution are required. Sold in a minimum order quantity of 100 pieces.

This washer is appropriate for metric M5 fastener applications across residential and light commercial construction, mechanical rooms, and equipment installations. The 18-8 stainless steel composition provides resistance to rust and oxidation, making it a practical choice for damp or corrosive environments. Installers working with sheet metal, enclosures, and thin-gauge brackets will find the wider bearing surface useful for maintaining joint integrity without the need for a backing plate.

Compatibility

Designed for use with M5 metric screws and bolts in applications requiring a fender-style washer per DIN 9021.

Installation Notes

Fender washers of this type are installed by general contractors, electricians, plumbers, and HVAC technicians as part of standard fastener assemblies. Ensure the mating fastener is also stainless steel or a compatible alloy to prevent galvanic corrosion. Do not overtighten fasteners against the washer face, as stainless steel is softer than hardened steel grades and may deform under excessive clamp load. Follow applicable mechanical or structural codes for the specific assembly.
