It features a 5\/8-11 UNC thread size and a 2-1\/4 inch length under head, manufactured from Grade 2 uncoated steel. The square head profile allows positive engagement with a wrench or fitting tool, making it a reliable choice in applications where hex-head access is limited or where the bolt must be held in place while a nut is driven. This fastener conforms to ANSI\/ASME B18.2.1 standards and weighs approximately 0.25 pounds.\u003c\/p\u003e\u003cp\u003eThis bolt is suited for use in light to medium duty structural, mechanical, and general maintenance applications. It is commonly used in wood framing connections, agricultural equipment, conveyor assemblies, and general fabrication where UNC threads and a square-drive head are specified. Trades including millwrights, ironworkers, maintenance mechanics, and general contractors routinely work with this fastener type. Sold individually, it fits applications requiring a single replacement or low-quantity procurement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-11 UNC thread for broad compatibility with standard coarse-thread nuts and tapped holes\u003c\/li\u003e\n\u003cli\u003e2-1\/4 inch length under head suits a range of material stack thicknesses\u003c\/li\u003e\n\u003cli\u003eSquare head profile provides positive wrench engagement in tight or offset installations\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003cli\u003eUncoated finish — suitable for dry interior environments or where field coating will be applied\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard coarse-thread square head bolt per ANSI\/ASME B18.2.1, compatible with any 5\/8-11 UNC nut or tapped hole meeting the same standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a properly sized open-end, box, or adjustable wrench rated for the bolt head size.
