It features a 3\/8-24 UNF thread with a 4-1\/2 inch length under head and a 5\/16 inch hex drive. The screw is partially threaded, allowing for positive clamping force between mating components. Constructed from alloy steel with a black oxide finish, it provides solid corrosion resistance in moderate service conditions. Licensed trades and maintenance professionals use this fastener in machine assembly, equipment repair, and structural component attachment where a recessed drive is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in precision mechanical assemblies, industrial machinery, and general maintenance applications requiring fine-thread engagement. The 3\/8-24 UNF thread pitch is commonly specified where vibration resistance or tighter thread engagement is needed compared to coarse-thread fasteners. The black oxide coating reduces light reflection and offers mild protection against corrosion in dry or lightly oiled environments. Typically installed by machinists, millwrights, or maintenance technicians working on equipment where socket-drive access is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF fine thread for tight, vibration-resistant engagement\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length under head for deep clamping or through-bolt applications\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch hex socket drive for use with standard Allen or hex key tooling\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides precise clamping and shear strength\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and general-use replacement hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574 specifications, suitable for any application requiring a 3\/8-24 UNF partially threaded socket cap screw with a 4-1\/2 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 5\/16 inch hex key or Allen driver.
