Built from alloy steel with a black oxide finish, this screw delivers solid mechanical strength and moderate corrosion resistance in a clean, low-profile head design. The 82-degree flat head seats flush with the mating surface when installed in a properly countersunk hole. Drive engagement is through a 9\/16-inch hex socket. At 7 inches overall length with partial threading, this fastener is suited for through-bolt and clamping applications in machinery, tooling fixtures, and structural assemblies where head protrusion is not acceptable.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in industrial, manufacturing, and maintenance settings wherever a countersunk socket drive fastener is required. The 7\/8-9 UNC thread pitch is a coarse-thread standard common in heavy-duty machine components, jigs, fixtures, and fabricated steel assemblies. Partial threading along the 7-inch shank allows for shank-bearing load transfer in close-tolerance bored holes. Machinists, millwrights, and maintenance mechanics are the primary installers in both production and MRO contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch hex socket drive for standard Allen wrench or socket tooling\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC coarse thread standard for broad compatibility with tapped holes\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear-load and close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength in demanding mechanical environments\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-specification fastener for applications requiring a 7\/8-9 UNC flat socket cap screw per ASME\/ANSI B18.3 and ASTM F835 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance mechanics using a 9\/16-inch hex key or socket driver. The mating hole must be countersunk to 82 degrees to achieve proper head seating and flush surface contact. Power down and de-energize any equipment before fastener replacement in live machinery. Do not exceed the rated torque range for the alloy steel grade being used, and verify thread engagement depth meets design requirements before final tightening.\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: 7 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: 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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3; 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: 1\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: 721530BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696014950706,"sku":"721530BR","price":32.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_51e701a6-1c6e-4a92-b41c-fb2a4429f8f1.jpg?v=1788339779","url":"https:\/\/voomisupply.com\/products\/value-collection-721530br-flat-socket-cap-screw-7-8-9-x-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
