Hot dip galvanizing provides a thick zinc layer that resists corrosion in outdoor and high-moisture environments, making these nuts well suited for structural and mechanical fastening where long-term weather exposure is a concern. The tapered oversize tolerance is standard for hot dip galvanized hardware, accommodating the added coating thickness so the nut threads correctly onto standard galvanized or uncoated bolts. Installers in electrical, plumbing, HVAC, and general construction trades keep these on hand for routine field assembly.\u003c\/p\u003e\n\u003cp\u003eThese hex nuts are used in residential and light commercial construction, outdoor equipment mounting, mechanical supports, pipe hangers, conduit strut work, and similar applications where a zinc-coated fastener is specified. The 5\/16-18 coarse thread size is one of the most common fastener sizes across trades and fits standard 5\/16-18 threaded rod, bolts, and studs. The 100-unit pack quantity suits service trucks, shop stock, and jobsite fastener bins.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized finish for heavy-duty corrosion resistance in outdoor and wet environments\u003c\/li\u003e\n  \u003cli\u003eTapered oversize thread tolerance accommodates galvanizing coating thickness on mating fasteners\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 coarse thread — one of the most widely used fastener sizes across mechanical trades\u003c\/li\u003e\n  \u003cli\u003e100-unit pack supports bulk stocking for service vehicles and job sites\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard wrenches and nut drivers for fast installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/16-18 threaded bolts, machine screws, and threaded rod, particularly those with a hot dip galvanized or zinc-coated finish where tapered oversize mating hardware is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThese nuts are installed by licensed trades and general contractors using standard combination wrenches, adjustable wrenches, or nut drivers. When used in structural or load-bearing applications, consult applicable building codes and torque requirements for the fastener grade specified. Do not mix hot dip galvanized hardware with dissimilar metals in corrosive environments without accounting for galvanic compatibility. Inspect threads before installation to confirm they are free of debris or damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot Dip Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Tolerance\u003c\/strong\u003e: Tapered Oversize\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: 9.45 pounds\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: 810506\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51560564719922,"sku":"810506","price":105.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f639fb150a5a71526b79f69d2e68dccc_e49029b1-34f8-4f6a-aaf4-f584524fcbc8.jpg?v=1786453917","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-810506-hex-nut-5-16-18-galvanized-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
