Value Collection A210025 M10 Fender Flat Washer 25-pack

Product Description

The VALUE COLLECTION A210025 is an M10 fender flat washer manufactured from Grade 18-8 stainless steel with a plain finish. Fender washers feature a larger-than-standard outside diameter relative to the inside diameter, distributing clamp load over a wider surface area to reduce pull-through in thin or soft materials. This washer conforms to DIN 9021 and is dimensioned in metric units, with a 10.5mm inside diameter and 30mm outside diameter. Each package contains 25 washers. Licensed tradespeople and maintenance professionals use these in plumbing, HVAC panel work, electrical enclosures, and general mechanical assemblies where corrosion resistance is required.

This washer is suited for both residential and light commercial applications wherever an M10 fastener is used and a wider bearing surface is needed. The 18-8 stainless steel construction makes it appropriate for moist or corrosive environments, including outdoor installations, wet mechanical rooms, pool equipment enclosures, and coastal service environments. The plain finish means no additional coating is applied, keeping tolerances consistent and avoiding contamination concerns in sanitary or food-adjacent settings.

Installation Notes

Install using standard hand tools appropriate for the M10 fastener being used. Ensure mating surfaces are clean and free of debris before seating the washer. When used in electrical enclosures or panel work, follow applicable NEC guidelines and de-energize the circuit before beginning work. Stainless steel fastener components can be susceptible to galling under high torque; apply appropriate anti-seize compound when specified by the fastener manufacturer.
