Flat washers distribute the load of a fastener across a broader surface area, reducing the risk of damage to the material being fastened and preventing nuts or bolt heads from pulling through. The wide pattern USS sizing provides greater bearing surface compared to standard SAE washers. These are a common stock item for contractors, plumbers, electricians, and general tradespeople working on structural and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis flat washer is suited for use in residential and light commercial construction, mechanical assemblies, HVAC equipment installation, plumbing rough-in, and electrical panel or conduit mounting applications. The 5\/16 inch inside diameter fits 5\/16 inch fasteners. Zinc plating provides corrosion resistance appropriate for indoor and protected outdoor environments. The 100-pack quantity is suited for contractors managing ongoing fastener inventory on the job site or in the shop.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch bore diameter fits standard 5\/16 inch bolts and screws\u003c\/li\u003e\n  \u003cli\u003eWide pattern USS specification provides greater load distribution than SAE pattern\u003c\/li\u003e\n  \u003cli\u003eZinc plated steel construction for corrosion resistance in typical service environments\u003c\/li\u003e\n  \u003cli\u003e100-pack quantity supports bulk use on active job sites\u003c\/li\u003e\n  \u003cli\u003eFlat washer design distributes clamping load and protects mating surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16 inch bolts, screws, and threaded fasteners in general construction, mechanical, and trade installation applications following USS wide pattern flat washer standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlat washers are installed between the fastener head or nut and the mating surface prior to tightening. Power down or de-energize any equipment before installing fasteners near electrical components. Use appropriate hand tools or power drivers; avoid over-torquing, which can deform the washer and reduce load distribution effectiveness. For outdoor or high-moisture environments, confirm that zinc plating provides adequate corrosion protection for the specific exposure conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc Plated Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePattern\u003c\/strong\u003e: Wide Pattern USS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 60.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HILLMAN FASTENERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 270058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51559874232626,"sku":"270058","price":345.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca7f3c9de18d98bd1a9e03da1ed721de_0c735a30-ae61-4897-9cdc-a2e379c58547.jpg?v=1786443180","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-270058-flat-washer-5-16-in-zinc-steel-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
