Value Collection 47390 M3 Flat Washer 18-8 Stainless Steel

Product Description

The VALUE COLLECTION 47390 is an M3 standard flat washer manufactured from Grade 18-8 stainless steel. It is designed to distribute load under a fastener head or nut, reduce surface damage, and prevent loosening during assembly. The washer measures 3.2mm inside diameter, 7mm outside diameter, and 0.5mm thick. With a hardness rating of 140 HV, it provides reliable performance in general mechanical assembly, maintenance, and fabrication applications. Machinists, maintenance technicians, and assembly professionals install these washers wherever corrosion resistance and dimensional consistency are required in metric fastener applications.

This washer is suited for light-duty to medium-duty fastening applications in residential, commercial, and industrial settings. The metric sizing makes it appropriate for equipment assembly, panel mounting, and fixture installations where M3 hardware is specified. It conforms to DIN 125, ISO 7089, and ISO 7090 fastener standards, making it a reliable choice for projects requiring documented compliance with internationally recognized specifications.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• Hardness of 140 HV for consistent load distribution without deformation under typical M3 fastener torque
• Conforms to DIN 125, ISO 7089, and ISO 7090 standards for dimensional and material compliance
• Metric sizing: 3.2mm ID, 7mm OD, 0.5mm thick for precise fitment on M3 fasteners
• Standard flat washer profile suitable for general-purpose assembly and maintenance work

Compatibility

Designed for use with M3 metric screws and bolts in applications requiring a standard flat washer per DIN 125, ISO 7089, or ISO 7090 specifications.

Installation Notes

Installation is performed by machinists, maintenance technicians, or assembly personnel using standard metric hand tools or power drivers. Ensure the washer is seated flat against the mating surface before tightening the fastener. Do not exceed the torque rating appropriate for M3 fasteners in the mating material. Inspect washers for deformation or corrosion before reuse in critical assemblies.
