Manufactured from alloy steel with a black oxide finish, this fastener provides corrosion resistance and reduced light reflection in service environments. It measures 12 inches in length under the head and uses a 3\/4-inch hex drive, making it compatible with standard hex keys and socket drivers. Conforming to ASME\/ANSI B18.3 and ASTM A574 standards, this screw is suited for applications where tensile strength and dimensional consistency are critical. Licensed trades and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fastener is appropriate for use in heavy-duty mechanical assemblies, equipment mounting, and structural bolting applications requiring a 7\/8-9 UNC thread form. The 12-inch length under head accommodates thick material stacks or deep-reach installations. The partial threading is typical for applications where a smooth shank is needed to pass through a clearance hole before engaging a tapped bore, providing better shear load distribution across the joint. It is well-suited for maintenance, repair, and original equipment manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread size for high-load fastening in standard unified coarse thread applications\u003c\/li\u003e\n  \u003cli\u003e12-inch length under head accommodates deep material stacks and long-reach installations\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 requirements for mechanical strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear load distribution in clearance-hole installations\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex drive compatible with standard hex keys and socket drive tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 compliant hex socket cap screw for use in any application requiring a 7\/8-9 UNC partially threaded fastener with a 12-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated torque wrench with a 3\/4-inch hex bit or hex key to achieve proper clamp load without yielding the fastener. Ensure the tapped bore is clean and free of debris before engagement. Power down and de-energize any associated equipment before performing fastener installation or removal in live assemblies. Follow applicable torque specifications from the equipment manufacturer or applicable ASME standards for 7\/8-9 UNC alloy steel fasteners.\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: 12 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: 0.05 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: 581767BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692657017138,"sku":"581767BR","price":39.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9b711e1e2d160d0dee19f95ab090963.jpg?v=1788300707","url":"https:\/\/voomisupply.com\/products\/value-collection-581767br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
