Fully threaded with a hex socket drive, it accepts a 7\/32-inch hex key for installation. The alloy steel construction meets ANSI\/ASME B18.3 and ASTM F835 standards, and the black oxide finish provides moderate corrosion resistance. Hardness is rated at 36-43 HRC, making this fastener suitable for medium-to-high-stress assemblies. It is installed by mechanical contractors, maintenance technicians, and machinists across a range of industrial and commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in mechanical assemblies, machine frames, equipment panels, and fixtures where a standard hex cap head would interfere with adjacent components. The button head profile reduces the risk of snagging or interference in tight clearance areas. The UNC thread form and Class 3A thread fit ensure a secure, consistent engagement with standard UNC tapped holes. Sold in a minimum order quantity of 50 pieces per package, this fastener suits both field repair and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile provides a low-profile, snag-resistant fastening surface\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC fully threaded, Class 3A thread fit for consistent engagement\u003c\/li\u003e\n  \u003cli\u003e7\/32-inch hex socket drive for standard hex key installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated at 36-43 HRC hardness\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for any application requiring a 3\/8-16 UNC button socket cap screw with a 2-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 7\/32-inch hex key or socket bit driver. Ensure the mating tapped hole meets UNC 3B tolerances before driving the fastener. Verify that the assembly surface is clean and free of debris to achieve full thread engagement.
