It features a 7\/8-9 UNC thread form and measures 3 inches in length under the head with full threading along the entire shank. The screw is machined from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection in precision assemblies. Drive engagement is via a 3\/4-inch hex socket. Installation requires a torque wrench or hex key set with a matching 3\/4-inch drive bit. This fastener is suited for use by millwrights, machinists, maintenance technicians, and general industrial trades.\u003c\/p\u003e\u003cp\u003eThis screw is used in applications where a clean, recessed drive head is required and bolt access is limited to a socket or Allen-type tool. Full threading along the 3-inch shank length allows engagement across varying material thicknesses and is well suited for through-bolting or threading into deeper tapped holes. Black oxide alloy steel construction makes it appropriate for dry or lightly oiled interior mechanical environments. It is commonly used in machine frames, jigs and fixtures, pump housings, and general industrial maintenance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC thread form for standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003eFully threaded 3-inch shank length provides maximum thread engagement flexibility\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex socket drive allows high torque application with standard tooling\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction delivers high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion resistance and a low-reflectance appearance\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or new-installation hex socket cap screw for any application requiring a 7\/8-9 UNC thread and a 3-inch length under head.

Verify thread condition in the mating tapped hole before installation and apply appropriate thread lubricant or anti-seize compound as required by the application. Do not use impact drivers at full speed for final seating, as this may damage threads or exceed alloy steel fastener specifications.\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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 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 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\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: 011503BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704632770866,"sku":"011503BR","price":23.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92a0858d93a84b10ad2e811846fc2d08.jpg?v=1788423946","url":"https:\/\/voomisupply.com\/products\/value-collection-011503br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
