Value Collection MSC-87925350 Flat Washer 18-8 Ss

Product Description

The VALUE COLLECTION MSC-87925350 is a standard flat washer manufactured from 18-8 stainless steel and sized for use with a number 12 screw. It features a 1/4-inch inside diameter, a 9/16-inch outside diameter, and a thickness of 0.065 inches. Flat washers in this configuration distribute load across a fastened joint, reduce surface damage under the fastener head or nut, and help prevent loosening caused by vibration. The 18-8 stainless steel construction provides solid corrosion resistance in moderate to mildly aggressive environments. This washer is produced to the ASME B18.22.1 1965 standard, making it a dependable choice for general-purpose fastening applications.

This washer is suited for residential and light commercial construction, plumbing fixture mounting, HVAC equipment assembly, electrical enclosure work, and general mechanical fastening wherever a corrosion-resistant hardware grade is required. Its inch-system dimensions make it compatible with standard imperial fastener assemblies. Installers and tradespeople typically use these washers in quantity on projects involving stainless fastener sets, sheet metal work, or any application where moisture exposure makes carbon steel washers unsuitable.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• Meets ASME B18.22.1 1965 standard for dimensional consistency
• 1/4-inch inside diameter fits number 12 screws in inch-system fastener assemblies
• 0.065-inch thickness provides reliable load distribution without excessive stack height
• 9/16-inch outside diameter gives adequate bearing surface for standard fastener heads and nuts

Compatibility

Designed as a standard replacement or new-installation flat washer for number 12 screw applications using inch-system fasteners, conforming to ASME B18.22.1 1965 dimensional requirements.

Installation Notes

Flat washers are installed between a fastener head or nut and the mating surface to distribute clamping load and protect the substrate. Verify the screw or bolt size matches the 1/4-inch inside diameter before assembly. When used in stainless fastener assemblies, consider applying an anti-seize compound to stainless threads to reduce the risk of galling. No special tools are required beyond standard hand or power drivers appropriate to the fastener type.
