It features a 5\/16-18 UNC thread with a 1-1\/4 inch length under the head and is driven by a 3\/16 inch hex socket. Manufactured from alloy steel with a black oxide finish, this fastener meets ANSI\/ASME B18.3 and ASTM F835 standards. Hardness is rated at 36-43 HRC, making it suitable for demanding mechanical assemblies where strength and a flush appearance are required. The fully threaded shank and Class 3A thread fit ensure consistent engagement across compatible tapped holes.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in general mechanical, industrial, and light structural assemblies where a button-head profile is preferred over a standard hex cap or flat-head fastener. The low-domed head reduces snagging on adjacent components and is commonly found in machine guards, panels, brackets, and fixtures. The black oxide coating provides mild corrosion resistance and a clean appearance in finished assemblies. Machinists, millwrights, and maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC fully threaded shank with Class 3A thread fit for consistent mating\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head suits moderate-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated 36-43 HRC for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low reflectivity\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex socket drive for use with standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC replacement or new-installation fastener for any tapped 5\/16-18 hole requiring a button socket cap screw per ANSI\/ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16 inch hex key or T-handle driver rated for the torque requirements of the application.
