It features a 1\/4-20 UNC thread with a 1-1\/2 inch length under the head, manufactured from Grade 2 uncoated steel. The square head profile allows wrench or pipe wrench engagement in tight spaces where a hex driver cannot be used. This bolt conforms to ANSI\/ASME B18.2.1 dimensional standards, making it a reliable choice for tradespeople who need consistent, code-referenced fasteners on the job.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for light-duty to medium-duty fastening tasks in HVAC equipment mounting, plumbing fixture framing, electrical enclosure assembly, and general mechanical work. The UNC thread form is the most common inch-series thread standard in North American trade applications, ensuring broad compatibility with standard nuts, threaded inserts, and tapped holes. The uncoated steel finish is appropriate for dry interior environments where corrosion resistance is not a primary requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head for common through-bolt and tapped-hole applications\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows engagement with adjustable wrenches and pipe wrenches\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 installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC square head bolt for use with any 1\/4-20 inch-series nut, threaded insert, or tapped hole conforming to ANSI\/ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using an adjustable wrench or appropriately sized open-end wrench on the square head.
