It features an 82-degree flat head driven by a 3\/16-inch hex socket, keeping the fastener head at or below the workpiece surface. The screw is partially threaded with a 5\/16-18 UNC thread size and an overall length of 3 inches. Manufactured from alloy steel with a black oxide finish, it provides corrosion resistance and reduces light reflection in finished assemblies. Licensed tradespeople and fabricators use this fastener where a clean, low-profile mechanical connection is required.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw suits general industrial, mechanical, and structural applications where a countersunk fastening profile is needed. The 5\/16-18 UNC thread pattern is a standard coarse-thread specification widely used in fabrication, machine assembly, and equipment mounting. The black oxide alloy steel construction handles moderate-stress applications where surface finish and flush seating matter. This item is sold in a package quantity of 25, with a minimum order quantity of 1 package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head for flush countersunk installation\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for precise torque application\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread, partially threaded shank\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for mechanical strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for corrosion resistance and low reflectivity\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 as a standard 5\/16-18 UNC flat socket cap screw suitable for use in any application requiring an 82-degree countersunk hex socket fastener per ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized countersink at 82 degrees to achieve a flush seating surface. Use a calibrated 3\/16-inch hex key or socket bit driver to drive the fastener. Avoid over-torquing, which can strip the socket or damage the countersink seat.
