It features a zinc yellow dichromate finish that provides corrosion resistance in demanding service environments. The screw is partially threaded and manufactured to ASME B18.2.1 and SAE J429 standards, ensuring dimensional accuracy and minimum tensile strength requirements associated with Grade 8 fasteners. It is installed by maintenance technicians, millwrights, pipefitters, and other trade professionals in structural, mechanical, and equipment assembly applications.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for heavy-duty bolted connections where high clamping force and reliable preload are required. Typical applications include machinery mounting, structural steel assembly, bracket and flange connections, and general industrial equipment fabrication. The partial threading allows for a full-shank bearing area in clearance holes, which is important in shear-loaded joints. Sold in a package quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets SAE J429 minimum tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a full grip length for shear-loaded applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.2.1 dimensional standards for consistent head geometry and thread tolerances\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 10, minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC inch-series hex nuts, heavy hex nuts, and tapped holes conforming to ASME B18.2.2 or equivalent specifications in structural and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tradespeople using a standard hex wrench, socket set, or torque wrench sized for a 1\/2-inch fastener. Always torque to the joint designer's specified value for Grade 8 fasteners rather than relying on generic estimates. Inspect threads and mating nut or tapped hole for damage or contamination before assembly. Use appropriate thread lubricant or anti-seize only when specified by the engineering requirement, as lubrication affects achieved clamp load at a given torque value.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\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: 10\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: C704248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693289341234,"sku":"C704248","price":58.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7a01c271a3727e2fc8028890687b8b6.jpg?v=1788310195","url":"https:\/\/voomisupply.com\/products\/value-collection-c704248-hex-head-cap-screw-1-2-13-x-9-in","provider":"Voomi Supply","version":"1.0","type":"link"}
