Value Collection SSWASHER1728 Flat Washer 316 Ss

Product Description

The VALUE COLLECTION SSWASHER1728 is a standard flat washer designed for use with 5/16 inch screws and fastener assemblies. Manufactured from Grade 316 stainless steel, this washer provides strong corrosion resistance in wet, marine, chemical-exposure, and outdoor environments. With an inside diameter of 11/32 inches, an outside diameter of 11/16 inches, and a thickness of 0.065 inches, it distributes load evenly across the fastened surface and helps prevent pull-through and surface damage. It is a standard-dimension washer suited to a wide range of mechanical, structural, and utility fastening applications where material integrity under exposure is a primary concern.

This washer is commonly used in plumbing, HVAC, pool and spa equipment, marine installations, and general industrial assembly where corrosion resistance is required. Grade 316 stainless steel is preferred over 304 in chloride-rich or chemically active environments, making this washer a practical choice for coastal, poolside, and process-piping applications. It is installed by plumbers, pipefitters, HVAC technicians, pool service professionals, and general maintenance trades as part of bolted or screwed connections requiring a durable, rust-resistant bearing surface.

Installation Notes

Installation is performed by qualified tradespeople or maintenance personnel using standard hand or power tools. Always ensure the fastener assembly is de-energized or depressurized before servicing any connected components. Place the washer flush against the mating surface with the fastener shank centered through the inside diameter before tightening. Follow applicable codes and fastener manufacturer torque guidelines for the specific joint being assembled.
