Sized at 7\/8-9 UNC with a 4-inch length under head, this screw is partially threaded and driven by a 3\/4-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and surface hardness suited for demanding environments. Mechanical contractors, millwrights, and maintenance technicians reach for this fastener when torque retention and material strength matter.\u003c\/p\u003e\u003cp\u003eThis cap screw is well suited for general industrial and commercial applications where high-tensile fasteners are required. The 7\/8-9 UNC coarse thread pattern seats efficiently in steel, cast iron, and similar substrates. Partial threading allows for greater shank strength in through-bolt and bearing-load scenarios. The black oxide coating reduces surface friction during installation and provides light-duty moisture resistance in indoor and controlled environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC coarse thread for reliable thread engagement in steel and iron\u003c\/li\u003e\n\u003cli\u003e4-inch length under head accommodates thicker material stacks\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank adds shear and tensile strength\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces galling and provides light corrosion protection\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex drive for use with standard socket or hex key tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 hex socket cap screw, suitable for use in tapped holes or with hex nuts in assemblies requiring 7\/8-9 UNC coarse thread fasteners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 3\/4-inch hex key or socket driver. Ensure the mating tapped hole or nut meets the 7\/8-9 UNC thread specification before installation. De-energize and lock out any equipment before fastener service on live machinery. Apply thread lubricant or anti-seize as required by the assembly specification to prevent galling on alloy steel threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 011509BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711953600818,"sku":"011509BR","price":17.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d35b735e5b982f67745e3b7d17ec6167.jpg?v=1788481865","url":"https:\/\/voomisupply.com\/products\/value-collection-011509br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
