Value Collection 93751 AN960 Flat Washer 5/16 Inch Stainless

Product Description

The VALUE COLLECTION 93751 is a standard flat washer manufactured to AN960 specification and intended for use with 5/16 inch screws. Built from stainless steel with a passivated finish, this washer distributes fastener load across a bearing surface to prevent pull-through and protect mating materials from corrosion. The 0.328 inch inside diameter provides a snug fit around a 5/16 inch fastener shank, while the 0.562 inch outside diameter delivers a reliable load-bearing footprint. At 0.063 inches thick, the profile stays within tight tolerance stacks common in aerospace, military, and industrial assemblies. Plumbers, HVAC mechanics, and maintenance technicians working with stainless hardware will find this washer meets AN960 and Military Specification C516 requirements.

This washer is suited for residential and commercial mechanical applications where corrosion resistance is required. Typical installations include pipe support hardware, equipment mounting, and structural fastening in damp or corrosive environments such as mechanical rooms, rooftop units, and pool equipment enclosures. The passivated stainless steel finish resists oxidation without added plating that could alter dimensional tolerances. This washer is sold individually with a minimum order quantity of 100 pieces, making it appropriate for stocking or batch hardware kits.

Installation Notes

Installation is performed by licensed tradespeople or qualified maintenance technicians using standard hand tools. Always de-energize or depressurize the assembly before disassembling fastened joints. Verify washer orientation so the bearing face seats flush against the mating surface. Do not substitute this washer in applications requiring a different fastener standard or nominal screw size without confirming dimensional compatibility.
