Value Collection 30716 Flat Washer 7/8 in Grade 316 Stainless Steel

Product Description

The VALUE COLLECTION 30716 is a standard flat washer designed for use with 7/8 inch screws and fasteners. Manufactured from Grade 316 stainless steel, it provides strong corrosion resistance in wet, chemical, and marine environments. The washer measures 15/16 inches inner diameter, 2-1/4 inches outer diameter, and 0.165 inches thick. These dimensions conform to standard inch-series flat washer geometry, making them a straightforward drop-in choice for structural, mechanical, and fluid-system assembly work. Plumbers, pipefitters, HVAC installers, and electricians working in corrosive or outdoor environments commonly specify Grade 316 hardware to meet project longevity requirements.

This flat washer is suited for residential and commercial applications where fastener load distribution and corrosion resistance are required. Typical uses include pipe flange connections, HVAC equipment mounting, pool and spa equipment installation, and marine or coastal construction. The Grade 316 alloy is preferred over Grade 304 in chloride-rich or salt-water environments due to its molybdenum content, which improves pitting resistance. These washers are sold individually but carry a minimum order quantity of 25 units per order.

Compatibility

Designed as a standard inch-series flat washer for use with 7/8 inch screws and bolts in mechanical, plumbing, HVAC, pool, and general construction assemblies.

Installation Notes

Install using standard hand tools appropriate for the fastener type. Ensure mating surfaces are clean and free of debris before assembly to maintain proper load distribution. When working on pressurized piping or energized equipment, follow applicable codes such as IPC or NEC and de-energize or depressurize the system before beginning fastener work. Do not mix stainless steel hardware with dissimilar metals in environments prone to galvanic corrosion without appropriate isolation measures.
