It features a 5\/8-11 UNC thread size and a 15-inch length under head, making it well suited for heavy-duty clamping and bolted joint applications where a long grip length is required. The screw is manufactured from alloy steel and finished with a black oxide coating, which provides mild corrosion resistance and reduces light glare on the fastener surface. Installation is performed using a 1\/2-inch hex drive key or hex bit. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is used across a broad range of industrial and trade applications including machine assembly, fixture building, tooling, and structural bolting. The partial thread configuration provides a bearing shank for accurate hole alignment and load transfer, which is preferred in through-bolt and dowel-adjacent installations. It is commonly installed by machinists, millwrights, maintenance technicians, and mechanical contractors working with heavy equipment, jigs, or steel-to-steel assemblies requiring a flush or low-profile fastener head.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread size for compatibility with standard coarse-thread tapped holes\u003c\/li\u003e\n  \u003cli\u003e15-inch length under head for long-reach or thick-stack fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a bearing surface for accurate alignment and shear load transfer\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers high tensile and yield strength per ASTM A574\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and a low-reflectance surface\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive for use with standard Allen keys or hex socket bits\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any 5\/8-11 UNC tapped hole application requiring a partially threaded alloy steel fastener with a 1\/2-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or mechanical technicians using a calibrated torque wrench and the appropriate 1\/2-inch hex key or hex bit. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or anti-seize as required by the joint specification.
