It features a 5\/8-11 UNC thread size and a 2-3\/4 inch length under head, machined from Grade 2 steel with an uncoated finish. The square head design allows for positive wrench engagement in tight clearance situations where a hex head may slip or be difficult to access. This bolt meets ANSI\/ASME B18.2.1 dimensional standards and is suited for structural and mechanical assembly work performed by millwrights, maintenance technicians, and general tradespeople.\u003c\/p\u003e\n\u003cp\u003eThis bolt is a practical choice for light-to-medium duty structural connections, machinery mounting, equipment frames, and utility installations. The 5\/8-11 UNC coarse thread pitch provides reliable engagement in steel, cast iron, and similar materials. The uncoated finish makes it appropriate for dry or protected indoor environments. Single-unit packaging allows for exact-quantity procurement without overstock, useful for service and repair scenarios where a single replacement fastener is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread for reliable engagement in standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 inch length under head for moderate grip range in structural and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows positive wrench engagement in confined spaces\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate tensile strength for light-to-medium duty loads\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for dry, protected indoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.2.1 dimensional standards for consistent fit and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC fastener compatible with any 5\/8-11 threaded nut or tapped hole conforming to ANSI\/ASME dimensional standards for coarse-thread series fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by millwrights, maintenance technicians, or general tradespeople using a standard open-end, box-end, or adjustable wrench sized for a square head profile.
