It is a standard fastener used to secure threaded assemblies across a wide range of mechanical, plumbing, and structural applications. The right-hand thread pattern conforms to Unified National Fine (UNF) standards. At 3\/4 inches across the flats and 7\/16 inches in height, this nut fits a standard 3\/4-inch wrench. The 18-8 stainless steel construction provides solid corrosion resistance in wet or mildly corrosive environments. Plumbers, pipefitters, HVAC technicians, and general tradespeople regularly stock this hardware for job-site use.\u003c\/p\u003e\u003cp\u003eThis hex nut suits residential and light commercial installations where a 1\/2-20 UNF fastener is required. Common applications include equipment mounting, pipe flange assemblies, bracket fabrication, and mechanical connections that call for corrosion-resistant hardware. The fine thread pitch provides strong clamping force and resistance to loosening under vibration. It is sold individually but carries a minimum order quantity of 100 pieces, making it practical for stocking in trade supply bins or job-lot ordering.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-20 UNF right-hand thread for reliable engagement with standard fine-thread fastener systems\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction offers corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no plating to chip or flake under torque\u003c\/li\u003e\n\u003cli\u003e3\/4 inches across the flats — fits a standard 3\/4-inch open-end or combination wrench\u003c\/li\u003e\n\u003cli\u003e7\/16 inches in height — standard hex nut profile for typical stack-up clearances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with any 1\/2-20 UNF male-threaded fastener or stud conforming to Unified National Fine thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this hex nut is straightforward and requires a 3\/4-inch wrench or socket. Always confirm that the mating bolt or stud is also 1\/2-20 UNF before assembly to avoid cross-threading. Do not mix stainless steel nuts with carbon steel fasteners in applications subject to galvanic corrosion risk. Tighten to the torque specification required by the equipment manufacturer or applicable code for the assembly in question.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF (Unified National Fine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0376 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691958337842,"sku":"3390","price":10479.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c7fd338ac22c0d9590089df0681bade.jpg?v=1788291417","url":"https:\/\/voomisupply.com\/products\/value-collection-3390-hex-nut-1-2-20-18-8-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
