Value Collection C24657 Sae Flat Washer 5/16 in 316 Ss

Product Description

The VALUE COLLECTION C24657 is an SAE flat washer designed for use with 5/16 inch fasteners. Manufactured from Grade 316 stainless steel, this washer provides strong resistance to corrosion and oxidation, making it well suited for wet, marine, and chemical-exposure environments. It measures 11/32 inches inner diameter, 11/16 inches outer diameter, and 0.083 inches thick. SAE flat washers distribute load across a fastener's bearing surface, reducing the risk of pull-through and surface damage on softer substrates. Licensed plumbers, pipefitters, HVAC technicians, and electricians reach for this hardware when stainless fastener assemblies call for a reliable, corrosion-resistant seating washer.

This washer fits standard 5/16 inch screw and bolt applications in residential and commercial settings. Common use cases include mechanical equipment mounting, pipe support assemblies, enclosure panel fastening, and outdoor or coastal installations where carbon steel hardware would corrode prematurely. The Grade 316 alloy, which contains molybdenum, performs well in chloride-rich and saltwater environments. It is sold individually per piece with a minimum order quantity of 50 units, making it appropriate for stocking in service vehicles or shop bins where volume fastener supply is needed.

Installation Notes

Installation is performed by any trade professional assembling or servicing mechanical, plumbing, electrical, or HVAC equipment. Always de-energize equipment and shut off fluid supply before disassembling fastened joints. Use appropriate hand tools and torque to the fastener manufacturer's specification for the given assembly. Avoid mixing stainless steel fasteners with dissimilar metals in direct contact where galvanic corrosion may be a concern.
