Value Collection A410352 M4 Flat Washer 316 Ss Din 125A 50-pack

Product Description

The VALUE COLLECTION A410352 is an M4 standard flat washer manufactured from Grade 316 stainless steel with a plain finish. Conforming to DIN 125A, this metric washer features a 4.3mm inside diameter and a 9mm outside diameter. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making it suitable for demanding environments including marine, chemical, and outdoor applications. Sold in a package of 50, this washer distributes load under bolt or screw heads and prevents surface damage during fastening. Plumbers, HVAC technicians, electricians, and general trade professionals use these washers in equipment assembly and structural fastening work.

This flat washer is intended for use with M4 metric screws and bolts in residential and commercial applications where corrosion resistance is a priority. Typical install scenarios include pipe hangers, equipment mounting, electrical panel work, and outdoor structural assemblies. The DIN 125A standard ensures consistent dimensional tolerances for repeatable fitment across metric fastening systems. Each package contains 50 washers, making this practical for job-lot stocking on service vehicles or shop benches.

Installation Notes

Install by licensed trades or qualified technicians in accordance with applicable mechanical and structural codes. Place the washer between the fastener head or nut and the mating surface before tightening to distribute clamp load. Ensure fastener threads and mating surfaces are free of debris before assembly. Do not mix Grade 316 and Grade 304 stainless hardware in environments where galvanic corrosion is a concern.
