It features right-hand threading conforming to the UN thread standard and meets ANSI\/ASME B18.2.2 dimensional requirements. Measuring 0.75 inches across flats and 0.4375 inches in height, this nut is sized for use with 1\/2-inch fine-thread fastener assemblies. Hardness is rated at Rockwell C32. Plumbers, HVAC technicians, electricians, and general trade professionals use this type of fastener in mechanical assemblies, equipment mounting, and structural connections requiring a reliable threaded joint.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is suited for residential and commercial trade applications where 1\/2-20 fine-thread fastening is required. It is commonly used in equipment installations, mechanical supports, pipe hanger assemblies, and other structural connections where a zinc-plated steel nut provides adequate corrosion protection in non-extreme environments. The fine thread pitch offers tighter thread engagement compared to coarse-thread equivalents, which can be advantageous in vibration-prone applications or when precise torque control is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 fine-thread specification with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eSAE J995 Grade 5 steel construction with Rockwell C32 hardness rating\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for general-duty corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.2.2 fastener dimensional standard\u003c\/li\u003e\n  \u003cli\u003e0.75 inches across flats — fits standard 3\/4-inch hex wrench or socket\u003c\/li\u003e\n  \u003cli\u003eUN thread standard for compatibility with unified national thread fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-20 fine-thread bolts and threaded rod conforming to the UN thread standard.

Ensure mating threads are clean and free of debris before assembly. Do not mix thread standards or pitch — confirm the mating fastener is also 1\/2-20 UN before installation. Follow applicable mechanical codes and torque specifications outlined in your project drawings or equipment manufacturer documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN (Unified National)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: SAE J995 Grade 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.2.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Rockwell C32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 0.866 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700195262770,"sku":"31215","price":1175.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7749b7820f3f14af63bf76dc6516002.jpg?v=1788387481","url":"https:\/\/voomisupply.com\/products\/value-collection-31215-hex-nut-1-2-20-grade-5-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
