Value Collection MSC-87925335 Standard Flat Washer No. 8

Product Description

The VALUE COLLECTION MSC-87925335 is a No. 8 screw standard flat washer manufactured from 18-8 stainless steel. It measures 3/16 inches inner diameter, 7/16 inches outer diameter, and 0.049 inches thick, conforming to ASME B18.22.1 1965. The 18-8 stainless steel construction provides corrosion resistance in wet, humid, or outdoor environments. This washer distributes clamping load evenly under a fastener head or nut, protecting mating surfaces and reducing the risk of loosening under vibration. Electricians, plumbers, HVAC technicians, and general mechanical tradespeople use flat washers like this in panel assemblies, equipment mounting, and pipe-support hardware.

This washer is suited for use with No. 8 screws in residential and light commercial applications where corrosion resistance is required. Common install scenarios include electrical enclosure assembly, HVAC equipment mounting, plumbing fixture attachment, and any structural or mechanical joint where a standard inch-series flat washer is specified. Its inch-system dimensions make it a direct fit wherever ASME B18.22.1 1965 standard washers are called out in engineering drawings or maintenance specifications.

Key Features

• 18-8 stainless steel construction for corrosion and oxidation resistance
• Conforms to ASME B18.22.1 1965 fastener standard
• 3/16 inch inner diameter fits No. 8 screw shank
• 7/16 inch outer diameter distributes load across mating surface
• 0.049 inch thickness provides consistent bearing surface without excessive stack height
• Inch system dimensioning for compatibility with standard imperial fastener layouts

Compatibility

Designed for use with No. 8 screws in standard inch-series fastener assemblies where ASME B18.22.1 1965 flat washers are specified.

Installation Notes

Install with hand tools standard to the trade; ensure the washer seats flat against the mating surface before final torque is applied to the fastener. Power down or de-energize any electrical assembly before introducing fasteners into an enclosure. Stainless steel fastener components should not be mixed with carbon steel hardware in the same joint to avoid galvanic corrosion risk. Minimum order quantity for this washer is 500 pieces per order increment.
