Value Collection 73019085-100 M3 Flat Washer 316 Ss

Product Description

The VALUE COLLECTION 73019085-100 is an M3 standard flat washer manufactured from Grade 316 stainless steel with a plain finish. Conforming to the DIN 125A fastener standard, this washer is designed to distribute load under bolt heads and nuts, reduce surface damage, and provide a stable bearing surface in metric fastener assemblies. Grade 316 stainless steel offers superior corrosion resistance compared to Grade 304, making it well suited for environments exposed to moisture, chemicals, or salt air. The metric sizing and DIN 125A compliance make this washer a direct fit in precision assemblies where standard dimensions are required.

This washer is used in a wide range of commercial, industrial, and marine applications where M3 metric fasteners are specified. Typical installation scenarios include electrical enclosures, HVAC equipment panels, pump housings, plumbing fixture assemblies, and any structural or mechanical assembly requiring a corrosion-resistant metric washer. It is suitable for use by mechanical contractors, millwrights, maintenance technicians, and trade professionals working with M3 fasteners in corrosive or high-humidity environments.

Key Features

• Grade 316 stainless steel construction for enhanced corrosion and chemical resistance
• Plain finish with no coating — ready for immediate use in corrosive environments
• Conforms to DIN 125A fastener standard for consistent metric dimensioning
• Sized for M3 screw applications in metric fastener assemblies
• Outside diameter of 7mm provides adequate load distribution for M3 fasteners
• Lightweight at 0.003 pounds per washer, minimizing added weight in assemblies

Compatibility

Designed for use with M3 metric fasteners in assemblies conforming to the DIN 125A standard. Suitable as a standard flat washer in any metric fastener application specifying an M3 screw size.

Installation Notes

Install by placing the washer over the M3 fastener before threading the nut or driving into the mating surface. Ensure the bearing surface is clean and free of debris before seating the washer. No special tools are required for washer installation, but fastener torque should follow the assembly specification for the M3 screw being used. Grade 316 stainless fastener assemblies should avoid contact with carbon steel hardware to prevent galvanic corrosion.
