It features a 5\/16-24 UNF thread size with a 3-inch length under head and is partially threaded. The drive type is hex with a 1\/4-inch drive size. Constructed from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and maintains integrity under torque loads. It conforms to ASME B18.3 and ASTM A574 standards. Licensed trades and maintenance professionals working on mechanical assemblies, equipment fabrication, and structural fastening applications rely on this grade of cap screw for consistent, repeatable performance.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in residential and commercial mechanical assemblies where a fine-thread UNF fastener is required. The 5\/16-24 UNF thread pattern is commonly used in applications requiring tighter thread engagement and reduced vibration loosening compared to coarse-thread alternatives. The black oxide finish provides a degree of surface protection appropriate for controlled indoor environments. This fastener is typically installed by machinists, millwrights, HVAC technicians, and general mechanical contractors during equipment assembly or field repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-24 UNF fine-thread specification for tighter thread engagement\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive socket interface\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for surface protection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 5\/16-24 UNF partially threaded fastener with a 1\/4-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanics or trade professionals using the appropriate 1\/4-inch hex key or socket driver.
