Value Collection A410351 M3 Flat Washer 316 Ss Din 125A 50-pack

Product Description

The VALUE COLLECTION A410351 is a standard flat washer designed for use with M3 metric fasteners. Manufactured from Grade 316 stainless steel with a plain finish, this washer provides corrosion resistance suited to demanding environments including marine, chemical, and food-service applications. It conforms to DIN 125A, the common metric standard for flat washers, making it a reliable choice for metric fastener assemblies. This pack contains 50 individual washers, sold as a single unit. Installation is performed by plumbers, pipefitters, maintenance mechanics, and general trade technicians working with metric hardware.

This washer is used in residential and light commercial applications wherever M3 metric screws or bolts require a load-distributing bearing surface. Typical scenarios include panel assembly, equipment mounting, and general mechanical fastening in corrosive or wet environments. The Grade 316 alloy, which contains molybdenum, offers superior pitting and crevice corrosion resistance compared to Grade 304, making it a preferred choice in salt-spray or chemical-exposure conditions.

Key Features

• Grade 316 stainless steel construction for enhanced corrosion resistance in marine and chemical environments
• Conforms to DIN 125A fastener standard for consistent metric dimensional compliance
• Plain finish with no coating or plating that could introduce galvanic incompatibility
• M3 screw size compatibility for use in precision metric assemblies
• Pack of 50 washers to support production or service inventory needs

Compatibility

Designed as a standard DIN 125A flat washer for use with M3 metric screws and bolts in metric fastener assemblies.

Installation Notes

Flat washers are installed by placing them against the bearing surface before tightening the fastener nut or bolt head. No special tools are required beyond standard wrenches or drivers appropriate to the mating fastener. In stainless steel assemblies, apply an anti-seize compound to mating fastener threads to prevent galling during torquing. Ensure the mating fastener material is compatible with Grade 316 stainless to avoid galvanic corrosion.
