It features a 1\/2-13 UNC thread size and an 8-inch length under head, manufactured from Grade 8 steel for high tensile strength and resistance to shear forces. The zinc yellow dichromate finish provides corrosion resistance in demanding service environments. This fastener conforms to ASME B18.2.1 standards, making it a reliable choice for structural, mechanical, and industrial assembly work performed by maintenance technicians, millwrights, pipefitters, and other trade professionals.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for industrial equipment assembly, structural steel connections, heavy machinery maintenance, and mechanical installations where Grade 8 strength is specified. The partial threading allows for improved clamp load distribution in thick-material assemblies. It is sold in packages of 10, making it practical for both single repairs and small-batch production or maintenance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread form ensures broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head accommodates thick material stacks and deep-reach fastening needs\u003c\/li\u003e\n  \u003cli\u003ePartial threading supports proper clamp load and reduces stress concentration in joint assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance in industrial and outdoor service conditions\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fit and function\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance fastener for applications requiring 1\/2-13 UNC hex head cap screws rated at Grade 8 strength in inch-series assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified technicians following applicable ASME, AISC, or equipment manufacturer torque specifications for Grade 8 fasteners at 1\/2-13 thread size. Always inspect mating threads for damage or contamination before installation. De-energize and lock out equipment before replacing structural fasteners in machinery. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts, as mismatched hardware can compromise joint integrity.\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: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\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: 39124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696512762162,"sku":"39124","price":41.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dc38a845fd60c30e10b09cf6206e8f3.jpg?v=1788343425","url":"https:\/\/voomisupply.com\/products\/value-collection-39124-hex-head-cap-screw-1-2-13-x-8-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
