It features an 82-degree flat head profile and a 5\/16-inch hex socket drive, allowing installation with a standard hex key or Allen driver. The fastener is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection on the fastener surface. The 1\/2-20 UNF thread is fully threaded along the 1-inch overall length. Machinists, millwrights, and mechanical contractors typically install these fasteners in precision assemblies where a low-profile, flush-seated head is required.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw suits applications where a standard hex cap screw head would protrude beyond the workpiece surface. The fully threaded 1-inch length and 1\/2-20 fine thread pitch are well suited for use in steel plates, machine frames, fixtures, and equipment guards. The black oxide alloy steel construction makes it appropriate for dry or lightly oiled indoor mechanical environments. Sold individually per package, with a minimum order quantity of 10 pieces.\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\u003e5\/16-inch hex socket drive for Allen key or hex bit installation\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF fully threaded, 1-inch overall length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 inch-series flat socket cap screw for use in any application requiring a 1\/2-20 UNF countersunk socket fastener in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a 5\/16-inch hex key or hex bit driver. Ensure the mating hole is countersunk to an 82-degree included angle to achieve full head seating. De-burr and clean the threaded hole before installation.
