Hot dip galvanized for superior zinc coating penetration, these nuts feature a tapered oversize profile that accommodates the additional coating thickness without compromising thread engagement. The coarse thread (1\/2-13 UNC) pattern provides reliable clamping force and is easy to thread by hand before final torque. Plumbers, electricians, HVAC technicians, and general contractors reach for this grade of nut when working in outdoor, underground, or moisture-exposed environments.\u003c\/p\u003e\u003cp\u003eThese hex nuts are suited for structural and mechanical fastening in residential and commercial construction, utility installations, equipment mounting, and trade rough-in work. The tapered oversize designation is standard for hot dip galvanized hardware, ensuring the nut will mate correctly with galvanized bolts and threaded rod of the same coating class. Each pack contains 50 nuts, making it practical for job-site replenishment or shop stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot dip galvanized finish provides heavy zinc coating for corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n\u003cli\u003eTapered oversize profile accommodates galvanized coating thickness on mating fasteners\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for fast hand-threading and broad fastener compatibility\u003c\/li\u003e\n\u003cli\u003e50-piece pack supports job-site and shop stock quantities\u003c\/li\u003e\n\u003cli\u003eHex drive style works with standard wrenches and impact sockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/2-13 UNC galvanized bolts and threaded rod. The tapered oversize thread form is the industry standard for hot dip galvanized hex nuts and is intended to mate with similarly coated 1\/2-13 fasteners per standard galvanized hardware practice.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand-threading the nut onto the mating bolt or threaded rod before tightening with a wrench or impact driver fitted with the correct socket. When used in structural applications, consult applicable building codes and engineer-specified torque requirements for the bolt grade and joint type. Avoid mixing galvanized and non-galvanized fasteners in the same joint to prevent accelerated galvanic corrosion. Inspect threads for damage before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\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\u003eProfile\u003c\/strong\u003e: Tapered Oversize\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 810512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51563859607858,"sku":"810512","price":143.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f639fb150a5a71526b79f69d2e68dccc_aae95666-9574-4777-b009-fdd51526b508.jpg?v=1786505244","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-810512-hex-nut-1-2-13-galvanized-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
