The screw features an 82-degree flat head with a 9\/16-inch hex socket drive and is fully threaded along its 2.5-inch overall length. Nominal thread size is 7\/8-9 UNC. Constructed from alloy steel with a black oxide finish, this fastener delivers solid mechanical strength and moderate corrosion resistance in controlled environments. Each package contains 5 screws. Ideal for maintenance, fabrication, and repair tasks handled by millwrights, machinists, and general mechanical trades.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machinery assemblies, fixtures, jigs, and structural fabrication where a countersunk socket drive fastener is required. The 82-degree flat head seats flush with the mating surface, eliminating protrusion in clearance-sensitive assemblies. The UNC thread form is the standard for inch-series fasteners used across industrial and commercial mechanical applications. The black oxide finish provides a low-reflectance appearance and light surface protection, making it a common choice in machine shops and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile seats flush with mating surface for clearance-sensitive assemblies\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch hex socket drive for use with standard hex keys or socket drive tools\u003c\/li\u003e\n  \u003cli\u003eFully threaded 7\/8-9 UNC along the full 2.5-inch overall length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength for demanding mechanical applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces surface glare and offers light corrosion protection in dry environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener for inch-series mechanical assemblies requiring a 7\/8-9 UNC fully threaded flat socket cap screw with an 82-degree countersink head profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance mechanics using a calibrated hex key or socket drive tool sized to the 9\/16-inch drive. Verify that the mating hole is countersunk to an 82-degree angle to ensure full head seating. De-energize or lock out all machinery before fastener removal or installation per applicable OSHA lockout\/tagout procedures. Do not substitute a hex key of incorrect size, as this may round the socket drive.\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\u003c\/strong\u003e: 2.5 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82-degree Flat\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: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: -48409-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51719274201394,"sku":"-48409-6","price":69.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4c233817b27ab2fa1787db2d29669fe.jpg?v=1788558541","url":"https:\/\/voomisupply.com\/products\/value-collection-48409-6-flat-socket-cap-screw-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
