Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean appearance suited to both exposed and concealed installations. The screw features a 1\/2-13 UNC thread with a 3\/8 inch hex drive socket and a 1\/2 inch length under head. Full threading along the shank provides consistent clamping force across the entire grip length. Sold in a package of 25, this fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding load-bearing applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in general-purpose mechanical assemblies, machine tool fixtures, equipment frames, and structural connections where a recessed hex drive is preferred over an external hex head. The black oxide coating makes it a common choice in applications where minimal light reflection or a finished appearance is required. Fully threaded construction suits thin-material connections and through-bolt configurations. Machinists, millwrights, maintenance technicians, and fabricators will find this screw applicable across a wide range of shop and field work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread for compatibility with standard unified coarse-thread tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank provides maximum thread engagement across the full 1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and a low-reflectance appearance\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive accommodates standard Allen or hex key tooling\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 dimensional standard for socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex socket cap screw suitable for use in any application requiring a fastener conforming to ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/8 inch hex key or Allen driver; ensure the driver is fully seated in the socket to avoid cam-out and socket damage.
