The partially threaded shank provides a bearing surface for load-bearing joints while the unified coarse (UNC) thread form ensures reliable engagement in standard tapped holes. Manufactured to ASME B18.2.1 dimensional standards, this screw ships in a bright, uncoated finish. It is installed by millwrights, maintenance mechanics, and industrial technicians wherever a heavy-duty inch-series fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy equipment assembly, structural steel connections, machinery frames, and other industrial applications that demand a high-tensile fastener. The 7\/8-9 UNC thread size and 8-1\/2 inch length under the head make it appropriate for bolting through thick steel plates, flanges, or stacked components. The bright finish is acceptable in dry or controlled environments where corrosion resistance is not a primary requirement.\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\u003ePartially threaded shank provides a grip length for shear-loaded joints\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread form for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no added plating thickness to affect thread fit\u003c\/li\u003e\n  \u003cli\u003e1-5\/16 inch hex key size for use with standard open-end, box, or impact wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 7\/8-9 UNC hex nuts, flat washers, and lock washers conforming to inch-series fastener standards.

Degrease mating surfaces and verify thread condition in the tapped hole or nut before assembly. Follow applicable torque specifications from your engineering drawings or fastener standards reference — do not estimate torque on Grade 8 hardware. Confirm the joint design accounts for the partially threaded shank length when calculating grip and thread engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8-1\/2 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\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\u003eHex Key Size\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 451164BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709306175794,"sku":"451164BR","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_75540563-533d-4cc9-8a95-69a42e099e63.jpg?v=1788454306","url":"https:\/\/voomisupply.com\/products\/value-collection-451164br-hex-cap-screw-7-8-9-x-8-5-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
