Built from Grade 8 steel in an uncoated finish, this fastener meets the dimensional and mechanical requirements of ASME B18.2.1 and SAE J429. The 1\/2-13 UNC thread size paired with a 6-1\/2-inch length under head makes it well suited for through-bolting thick stock or deep-clearance connections. The partial threading allows for a smooth shank section that improves shear resistance in bolted joints. Installers and maintenance technicians across mechanical, HVAC structural, and general trade applications rely on Grade 8 fasteners where high tensile and proof-load strength are required.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in residential and commercial construction, equipment mounting, machinery assembly, and mechanical system structural connections. It is appropriate for any application requiring a high-strength inch-series hex cap screw with a 1\/2-13 UNC thread form. The partial thread configuration is especially common in flange connections, frame bolting, and equipment base plate installations where the smooth shank must pass through one or more members before engaging the threaded section.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets SAE J429 mechanical property requirements for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread form per ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003e6-1\/2-inch length under head accommodates deep-reach and through-bolt applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides improved shear load performance in bolted joints\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with applied coatings or in interior dry environments\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use fastener for applications requiring a 1\/2-13 UNC hex head cap screw in Grade 8 steel with a 6-1\/2-inch length under head per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with proper torque procedures for Grade 8 fasteners. Always use a calibrated torque wrench and follow the applicable joint design specification for the required clamp load. Do not mix Grade 8 fasteners with lower-grade nuts or hardware that does not match the specified proof load. Uncoated fasteners used in corrosive or outdoor environments should receive an appropriate protective coating or be paired with compatible hardware rated for that exposure.\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: 6-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: KP45584\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696400892210,"sku":"KP45584","price":36.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88180bc8feb79603c537ee590f38026c.jpg?v=1788342259","url":"https:\/\/voomisupply.com\/products\/value-collection-kp45584-hex-cap-screw-1-2-13-x-6-1-2-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
