It features a 1\/2-13 UNC thread size with a 3\/8 inch length under the head and is fully threaded from head to tip. The screw is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. A 3\/8 inch hex drive is required for installation. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it a recognized choice for demanding fastening tasks in fabrication, maintenance, and mechanical assembly work.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in equipment maintenance, machine assembly, tooling fixtures, and general industrial fastening where a high-strength, socket-drive cap screw is required. Its fully threaded design and black oxide finish make it appropriate for both ferrous and non-ferrous assemblies where precise clamping load is needed. Machinists, millwrights, maintenance technicians, and fabricators are the primary installers of this fastener type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size for standard unified coarse thread engagement\u003c\/li\u003e\n\u003cli\u003e3\/8 inch length under head, fully threaded\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003cli\u003eHex socket drive requires a 3\/8 inch hex key or socket bit\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex socket cap screw for use in any application requiring an ASME\/ANSI B18.3 and ASTM A574 compliant fastener of this thread size and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly sized 3\/8 inch hex key or socket drive tool.
