Featuring a 7\/8-9 UNC thread and a 3\/4-inch hex drive, this fastener is partially threaded with a 3-1\/4-inch length under head. Constructed from alloy steel with a black oxide coating, it delivers corrosion resistance and surface hardness suited to demanding service environments. It meets ASME\/ANSI B18.3 and ASTM A574 standards, which govern dimensional tolerances and mechanical strength requirements for socket cap screws. Machinists, millwrights, and maintenance mechanics commonly install this type of fastener.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in heavy equipment assembly, machine bases, fixtures, and structural bolted connections where a recessed hex drive is preferred over an external hex head. The 7\/8-9 UNC coarse thread engages quickly and resists stripping in through-hole or tapped applications. The black oxide finish makes it suitable for indoor industrial environments where moderate corrosion resistance is acceptable. It is sold individually and is a common replacement or stock fastener for shop and field maintenance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC coarse thread for fast engagement and reliable clamp load\u003c\/li\u003e\n  \u003cli\u003e3-1\/4-inch length under head — partially threaded for shank grip in through-bolt applications\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex socket drive for use with standard hex keys or socket drive tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength socket screw requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces galling during installation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw suitable for tapped or through-hole assemblies requiring a 7\/8-9 UNC thread and a recessed hex drive configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance mechanics using a 3\/4-inch hex key or socket drive tool. Ensure the mating tapped hole or nut meets 7\/8-9 UNC thread specifications before driving. Apply appropriate thread lubricant or anti-seize compound based on the service environment and torque to the assembly engineer's specified value. De-energize and lock out all equipment before accessing fastener locations on live machinery.\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: 3-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/4 inch\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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.3, 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: 011505BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712821494066,"sku":"011505BR","price":17.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afa79d175fe9731bd10ac42e42b63df9.jpg?v=1788488809","url":"https:\/\/voomisupply.com\/products\/value-collection-011505br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
