It features a 5\/8-11 UNC thread size and measures 5 inches in length under the head. Manufactured from Grade 2 steel with an uncoated finish, this bolt meets ANSI\/ASME B18.2.1 dimensional standards. The square head profile allows positive wrench engagement and is well suited for applications where a wrench must grip in tight or awkward spaces. Installers working in fabrication, construction framing, and mechanical assembly rely on this style of fastener where a standard hex head is not preferred or specified.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used across a range of trade and industrial applications including structural steel connections, machinery mounting, HVAC equipment framing, and plumbing fixture support. The 5\/8-11 UNC coarse thread provides reliable engagement in standard tapped holes and nuts. The uncoated steel finish is appropriate for interior, dry, or protected environments where corrosion exposure is limited. Typical installers include ironworkers, pipefitters, millwrights, and general contractors working on light structural or mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread for use with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e5 inches length under head provides adequate thread engagement for thick structural members\u003c\/li\u003e\n  \u003cli\u003eSquare head profile for positive wrench grip in confined or awkward spaces\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 or protected interior applications\u003c\/li\u003e\n  \u003cli\u003eSold individually — package quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ANSI\/ASME B18.2.1 square head bolt for use with 5\/8-11 UNC nuts and hardware in general structural and mechanical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tradespeople using an appropriate open-end, box-end, or adjustable wrench sized for the square head.
