This partially threaded fastener conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for structural and mechanical assemblies that require a fastener with a bearing surface under the hex head. The zinc plating provides a baseline level of corrosion resistance for general indoor and moderate-exposure applications. It is sized for use with a standard 3\/4-inch wrench and pairs with 1\/2-13 UNC threaded holes or nuts.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for a wide range of trade and industrial applications, including equipment mounting, bracket fabrication, HVAC unit assembly, mechanical supports, and general structural connections. Partial threading provides a smooth shank section that resists shear loads, making it appropriate where the fastener passes through a clearance hole before engaging a threaded mate. Tradespeople across HVAC, plumbing, and electrical disciplines routinely use Grade 5 hex cap screws for equipment installation and structural support work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form, partially threaded with smooth shank section for shear-load resistance\u003c\/li\u003e\n  \u003cli\u003e3-inch length measured under the head per ASME B18.2.1 specification\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for medium-strength fastening requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in general-duty environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC threaded nuts, inserts, and tapped holes in general mechanical, structural, and equipment-mounting assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson using the appropriate 3\/4-inch wrench or socket. Always verify thread engagement and ensure the mating threaded hole or nut is clean and free of debris before assembly. Do not over-drive; tighten to the torque specification required by the application or equipment manufacturer. When used in safety-critical or load-bearing structural connections, follow applicable codes and engineering requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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 Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensional Standard\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\u003eWeight\u003c\/strong\u003e: 0.01 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: D30112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720843788594,"sku":"D30112","price":31.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/377e639eb8a033c033f5454bc4bbc7b6.jpg?v=1788569844","url":"https:\/\/voomisupply.com\/products\/value-collection-d30112-hex-head-cap-screw-1-2-13x3-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
