It features a 5\/16-24 UNF thread and a 1\/2-inch length under head, with a low-profile button head that reduces snag points in assembled components. Driven by a 3\/16-inch hex socket, the screw is manufactured from alloy steel and finished in black oxide for corrosion resistance. Hardness is rated at 36-43 HRC, making it suitable for medium-to-high-strength fastening tasks. This listing covers a package of 50 screws with a minimum order quantity of 1 package.\u003c\/p\u003e\n\u003cp\u003eButton socket cap screws of this configuration are commonly used in machine assemblies, equipment panels, jigs, fixtures, and fabricated enclosures where a low-profile head is required. The 5\/16-24 UNF thread pitch provides fine adjustment and strong clamp load in metal-to-metal applications. This screw is typically installed by machinists, millwrights, maintenance technicians, and fabricators working on light to medium industrial equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-24 UNF fully threaded, right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch length under head for compact fastening depth\u003c\/li\u003e\n  \u003cli\u003eLow-profile button head minimizes protrusion in assembled parts\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for standard Allen key or hex bit installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with black oxide finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHardness rated 36-43 HRC per ASTM F835 and ANSI\/ASME B18.3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF-thread fastener compatible with 5\/16-24 tapped holes in metal assemblies, fixtures, and mechanical components per ANSI\/ASME B18.3 and ASTM F835 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 3\/16-inch hex key or hex socket bit.
