The screw features a 7\/8-9 UNC thread and measures 14 inches in length under the head, making it well suited for deep-reach bolting in heavy equipment and machinery. It is partially threaded, which distributes clamping load effectively along the shank. Constructed from alloy steel and finished with a black oxide coating, it offers increased hardness and moderate corrosion resistance. Millwrights, maintenance mechanics, and fabricators install these fasteners in production and repair settings.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in industrial manufacturing, heavy equipment maintenance, structural fabrication, and general mechanical assembly. The 7\/8-9 UNC thread size is a standard coarse-thread designation common in North American industrial equipment. The 3\/4 inch hex drive is compatible with standard hex keys and socket drive tools. Partially threaded shanks are preferred when clamping unthreaded material between a bearing surface and a mating threaded component. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding load-bearing joints.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC coarse-thread specification for high-clamping-load applications\u003c\/li\u003e\n  \u003cli\u003e14 inch length under head accommodates deep-reach or thick-stack assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides full shank bearing surface for shear-load joints\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers high tensile and proof-load strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension hex socket cap screw for any application requiring a 7\/8-9 UNC coarse-thread fastener with a 3\/4 inch hex drive and a 14 inch length under head per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by millwrights, maintenance mechanics, or qualified assemblers using a 3\/4 inch hex key or hex socket drive tool. Ensure the mating tapped hole or nut thread specification matches 7\/8-9 UNC before installation. De-energize and lock out all equipment per applicable OSHA lockout\/tagout procedures before fastener installation or removal. Do not substitute a lower-grade fastener in joints designed to ASTM A574 specification.\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: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0024 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: 581769BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721504489778,"sku":"581769BR","price":35.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f8d6f44e9ee46781cd26bc538ad40df.jpg?v=1788578226","url":"https:\/\/voomisupply.com\/products\/value-collection-581769br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
