Manufactured from Grade 2 uncoated steel, this bolt features a 1\/2-13 UNC thread and measures 3-1\/2 inches in length under the head. The square head profile allows for positive wrench engagement in tight or high-torque installations. It meets ANSI\/ASME B18.2.1 dimensional standards and is supplied uncoated. Licensed tradespeople and maintenance technicians working in mechanical, construction, and industrial settings routinely specify this fastener type for fixed structural connections.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for general mechanical assembly, steel fabrication, wood-to-steel connections, and equipment mounting where a square head profile provides installation advantages. The partially threaded shank maintains a smooth bearing surface along the unthreaded portion, which helps resist shear loads at the joint. Typical applications include framing connections, machinery bases, and utility structure assembly. This fastener is sold with a minimum order quantity of 25 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC right-hand thread for standard nut and tapped-hole compatibility\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a smooth shear-bearing surface\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows firm wrench engagement in high-torque applications\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 indoor environments or where field coating will be applied\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension ANSI\/ASME B18.2.1 square head bolt for use with 1\/2-13 UNC hex nuts, square nuts, and tapped holes in structural and mechanical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, ironworkers, or maintenance mechanics using standard open-end or box wrenches sized for a 1\/2-13 square head bolt. Verify that the mating nut or tapped hole thread specification matches 1\/2-13 UNC before installation.
