Each nut features a tapered oversize profile, which accommodates the added zinc thickness from the galvanizing process and ensures proper thread engagement on galvanized bolts and threaded rod. These nuts are a standard fastener choice for outdoor, structural, and corrosive-environment applications where long-term corrosion resistance is required. Plumbers, electricians, HVAC installers, and general construction trades rely on galvanized hex nuts for equipment mounting, pipe strut work, and equipment support frames exposed to moisture or weather.\u003c\/p\u003e\n\u003cp\u003eThese 3\/8-16 hex nuts are suited for residential and commercial construction, mechanical equipment mounting, pipe hanger systems, and outdoor structural assemblies. The coarse thread pattern is the standard for general-purpose fastening and works with 3\/8-16 galvanized bolts, all-thread rod, and carriage bolts. The tapered oversize specification is required when mating with hot dip galvanized externally threaded fasteners, as standard nuts will not engage correctly after coating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized finish provides heavy-duty corrosion resistance for outdoor and wet environments\u003c\/li\u003e\n  \u003cli\u003eTapered oversize profile designed specifically for use with hot dip galvanized bolts and threaded rod\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 coarse thread — the most common thread spec for general structural fastening\u003c\/li\u003e\n  \u003cli\u003e100-pack quantity reduces downtime on multi-connection jobs\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard wrenches and socket sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8-16 hot dip galvanized bolts, carriage bolts, and all-thread rod.

Verify that mating bolts or threaded rod carry the same hot dip galvanized finish and 3\/8-16 coarse thread designation before installation. Use a properly sized wrench or socket to achieve a snug, secure fit. Follow applicable building and mechanical codes for structural fastener torque and connection requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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\u003eDrive Type\u003c\/strong\u003e: Hex\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: 13.5 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: 810509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51560351170866,"sku":"810509","price":129.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f639fb150a5a71526b79f69d2e68dccc_87df5030-7249-4b22-a692-9e752ab89de3.jpg?v=1786451039","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-810509-3-8-16-hex-nut-galvanized-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
