The UNF thread form and ASME B18.2.1 compliance make it a standard choice for general mechanical fastening in trade and industrial applications. The zinc coating provides basic corrosion resistance for use in typical shop and field environments. Length is measured under the head at 4-1\/2 inches. This fastener is used by maintenance technicians, pipefitters, millwrights, and general tradespeople who need a reliable inch-series hex cap screw for structural or equipment assembly work.\u003c\/p\u003e\u003cp\u003eThis screw suits residential and commercial mechanical, HVAC, and equipment mounting applications where a 1\/2-20 UNF thread engagement is required. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for bolted joints where shank fit to hole clearance matters. It is compatible with standard 1\/2-20 UNF nuts and tapped holes conforming to ASME thread standards. Sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-20 UNF thread form for fine-thread engagement\u003c\/li\u003e\n\u003cli\u003e4-1\/2 inch length under head for deep fastening applications\u003c\/li\u003e\n\u003cli\u003eGrade 5 steel construction for medium-strength bolted joints\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for shear-load bearing capability\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2-20 UNF nuts, washers, and tapped holes conforming to ASME inch-series thread standards in general mechanical and trade assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by any trade professional using standard hex wrenches or socket drivers sized for a 1\/2-inch hex cap screw. Ensure mating threads are clean and free of debris before fastening. Do not over-torque; consult applicable equipment manufacturer specifications or relevant ASME or industry torque tables for Grade 5 fasteners. Always de-energize and isolate any equipment before performing fastener work on live assemblies.\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\u003eLength Under Head\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: Grade 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D30292\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717458592050,"sku":"D30292","price":36.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1236d53b515ead66fe2df12264fd0903.jpg?v=1788540798","url":"https:\/\/voomisupply.com\/products\/value-collection-d30292-hex-head-cap-screw-1-2-20-x-4-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
