With a 7\/8-14 UNF thread size and a 7-inch length under head, this partially threaded fastener delivers the clamping force and thread engagement required for demanding bolted joints. The bright, uncoated finish maintains dimensional accuracy without added coating thickness. It conforms to ASME B18.2.1 standards, making it a recognized choice for engineers and tradespeople who need a verified specification on the job.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for applications where a fine-thread, high-strength fastener is required, including heavy equipment assembly, machinery mounting, and structural steel connections. The 7\/8-14 UNF thread pitch provides greater thread engagement per inch compared to coarse-thread equivalents, which is useful in applications subject to vibration or where precise torque control is critical. Machinists, millwrights, and industrial maintenance technicians commonly install this type of fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e7\/8-14 UNF fine-thread specification for improved vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for precise bearing surface clamping\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains close dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for verified dimensional compliance\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex key size for standard wrench engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.2.1-compliant hex head cap screw suitable for use in any application requiring a 7\/8-14 UNF Grade 8 partially threaded fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, mechanics, or maintenance technicians using a standard 1-9\/16-inch open-end, box-end, or socket wrench. Always verify hole thread condition and fastener grade compatibility before installation. Follow applicable engineering specifications or torque tables for Grade 8 hardware of this diameter and thread pitch. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts not rated for the corresponding load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 7 inches\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 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: 451171BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714564161842,"sku":"451171BR","price":26.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/feadd48e80d5c05a23d56319dbe66784.jpg?v=1788503244","url":"https:\/\/voomisupply.com\/products\/value-collection-451171br-hex-head-cap-screw-7-8-14-x-7-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
