It features a 5\/8-11 UNC thread with a 5-1\/2 inch length under the head and is partially threaded for proper load engagement. The alloy steel construction with a black oxide finish provides corrosion resistance and surface hardness. The 1\/2 inch hex drive accommodates standard hex keys and socket wrenches. This fastener meets ASME B18.3 and ASTM A574 standards, making it suitable for structural and mechanical assembly work performed by machinists, maintenance technicians, and industrial tradespeople.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in heavy equipment assembly, machine frames, industrial fixtures, and structural connections where a recessed drive and high tensile strength are required. The partial threading allows for firm clamping force between mated parts. It is commonly installed in both fabrication shop environments and field maintenance settings where high-load fastener specifications are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread for standard inch-series fastening applications\u003c\/li\u003e\n  \u003cli\u003e5-1\/2 inch length under head with partial threading for strong clamping engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength socket screw requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces surface glare\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch hex socket drive compatible with standard hex keys and drive tools\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME 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 an OEM-style replacement or standard-spec fastener for industrial machinery, structural assemblies, and mechanical fixtures requiring 5\/8-11 UNC hex socket cap screws per ASME B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician using the correct 1\/2 inch hex key or socket driver.
