The screw features a 3\/4-16 UNF thread size with a 2-1\/2-inch length under the head and a 5\/8-inch hex drive socket. It is fully threaded, providing maximum thread engagement across the full shank length. Manufactured from alloy steel with a black oxide coating, this fastener meets ASME\/ANSI B18.3 and ASTM A574 standards. It is installed by machinists, millwrights, and maintenance technicians in industrial environments.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for applications requiring precise thread engagement and high tensile strength, including fixture plates, hydraulic component mounting, machine frames, and jig assemblies. The fine 3\/4-16 UNF thread pitch allows for tighter preload control compared to coarse-thread equivalents, making it appropriate for high-vibration environments and precision assemblies where controlled clamping force is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF fine-thread profile for precise torque and preload control\u003c\/li\u003e\n  \u003cli\u003e2-1\/2-inch length under head with full threading along the entire shank\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex drive socket for standard Allen key or socket wrench installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated to ASTM A574 for high tensile and proof-load strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion resistance and reduces surface glare\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 3\/4-16 UNF fully threaded alloy steel fastener with a 5\/8-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician using a 5\/8-inch hex key or socket driver. Verify that the mating tapped hole conforms to the 3\/4-16 UNF thread specification before installation to prevent cross-threading or galling. Apply appropriate thread lubricant or anti-seize compound as required by the assembly specification.
