It features an 82-degree flat head driven by a 3\/16-inch hex socket, making it compatible with standard Allen wrenches and hex key sets. Manufactured from alloy steel with a black oxide finish, this screw offers good mechanical strength and moderate corrosion resistance in dry or lightly oiled environments. The 5\/16-18 UNC thread is fully threaded along the 1\/2-inch overall length. It meets ASME\/ANSI B18.3 and ASTM F835 fastener standards. Installers in mechanical, HVAC, electrical, and industrial maintenance trades use this type of fastener when a low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machine assemblies, equipment panels, brackets, and structural components where a countersunk seating surface is present. The 5\/16-18 UNC thread is one of the most common inch-series coarse thread specifications, making the 36821 a straightforward drop-in for general mechanical and trade service work. The black oxide finish blends into ferrous assemblies and provides a modest level of surface protection. It is sold individually but carries a minimum order quantity of 25 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for Allen wrench or hex bit installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides light corrosion resistance and low reflectivity\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC along the full 1\/2-inch length\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series flat socket cap screw for use in any application requiring a 5\/16-18 UNC countersunk fastener with a hex socket drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/16-inch hex key or hex socket bit.
