It features an 82-degree flat head with a 9\/16-inch hex socket drive and measures 7\/8-9 thread size by 4 inches in overall length. The screw is partially threaded and manufactured from alloy steel with a black oxide finish, which provides moderate corrosion resistance and a clean appearance. It is sized for heavy-duty mechanical assemblies and is installed by machinists, millwrights, and maintenance technicians working on equipment where standard cap screws would protrude above the mating surface.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for use in machine frames, tooling fixtures, structural assemblies, and industrial equipment requiring countersunk fasteners. The 7\/8-9 UNC thread size is a common coarse-thread pitch used in general engineering and manufacturing applications. The partial threading allows for a shank section that can bear shear loads, making it appropriate for joints where alignment and load transfer are critical alongside clamping force.\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 secure wrench engagement\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC coarse thread, partially threaded for shear-load capability\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to 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 a standard UNC coarse-thread flat socket cap screw suitable for countersunk fastening applications in industrial machinery, tooling, and structural assemblies requiring a 7\/8-9 threaded fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly countersunk or flat-bottom bored hole machined to accommodate the 82-degree head angle.
