It features an 82-degree flat head with a 3\/8-inch hex socket drive, accepting a standard hex key for installation and removal. The screw is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection. The 5\/8-11 UNC thread and 1-3\/4-inch overall length are fully threaded, maximizing thread engagement in blind or through-hole applications. Machinists, millwrights, and maintenance technicians use this type of fastener in machinery, fixtures, and structural assemblies where a protruding head is not acceptable.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is suited for industrial and mechanical applications where a countersunk seat is already machined or stamped into the mating part. Typical uses include machine frames, jigs, fixtures, conveyor components, and fabricated steel assemblies. The fully threaded configuration is particularly useful in thinner material stacks where partial threading would leave unthreaded shank in the grip area. The black oxide finish is appropriate for interior or low-moisture environments. Meets ASME\/ANSI B18.3 and ASTM F835 fastener standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head seats flush in standard countersunk holes\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for reliable torque transfer with a hex key or bit\u003c\/li\u003e\n\u003cli\u003eFully threaded 5\/8-11 UNC for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces surface glare and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension replacement or stock fastener for any application calling for a 5\/8-11 UNC flat socket cap screw with an 82-degree head angle per ASME\/ANSI B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 3\/8-inch hex key or hex bit driver. Ensure the mating countersink is machined to an 82-degree included angle to achieve proper head seating before applying final torque.
