It features a 3\/4-16 UNF thread, a 2.25-inch length under head, and a 5\/8-inch hex drive socket. The screw is fully threaded and manufactured from alloy steel with a black oxide finish that provides mild corrosion resistance and a clean, low-reflectance appearance. It conforms to ASME B18.3 and ASTM A574 standards, making it suitable for structural and mechanical applications where torque load capacity and dimensional precision are required. Machinists, millwrights, and maintenance mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in industrial machinery, hydraulic equipment, structural steel assemblies, and precision mechanical components where a recessed-drive fastener is preferred over a hex head. The fine 3\/4-16 UNF thread pitch provides tighter thread engagement and improved resistance to vibration loosening compared to coarse thread equivalents. It is well suited for ferrous metal applications and assemblies that require controlled clamp load.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e2.25-inch length under head fits medium-depth through-bolt and tapped-hole applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex socket drive for high torque input with standard Allen keys or hex bit sockets\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces surface glare\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock hex socket cap screw for industrial and mechanical assemblies requiring a 3\/4-16 UNF fully threaded fastener per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified maintenance personnel using a 5\/8-inch hex key or driven bit socket.
