It features an 82-degree flat head with a 3\/16-inch hex socket drive and a 5\/16-18 UNC thread on a 1-3\/4-inch overall length. The fastener is fully threaded and manufactured from alloy steel with a black oxide finish, providing moderate corrosion resistance and reduced light reflection. Machinists, millwrights, fabricators, and maintenance technicians install this style of fastener where a smooth, low-profile surface is required after assembly.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for use in machine components, fixtures, jigs, and mechanical assemblies where a protruding head is not acceptable. The 5\/16-18 UNC thread is a common inch-series coarse thread, compatible with standard tapped holes and threaded inserts across a wide range of industrial and OEM applications. The black oxide finish makes it a practical choice in environments where glare reduction or a clean finished appearance is preferred alongside adequate surface protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC fully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and low-glare appearance\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 for use in standard 5\/16-18 UNC tapped holes and countersunk bores with an 82-degree included angle, as specified by ASME\/ANSI B18.3 for flat socket cap screws in inch-series applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a properly sized 3\/16-inch hex key or socket driver to avoid rounding the drive recess. Ensure the mating hole is countersunk to the correct 82-degree angle and depth to achieve a fully flush seating surface.
