Threaded 7\/8-9 UNC with a 3-1\/2 inch length under the head, this bolt is manufactured from Grade 2 steel with an uncoated finish. The square head profile provides high torque transfer capability and is well-suited for use in wood construction, agricultural equipment, and industrial assemblies where a standard hex head may not be practical. Installation is typically performed by millwrights, ironworkers, or general contractors working in structural or equipment-mounting applications.\u003c\/p\u003e\u003cp\u003eThis bolt is used in residential, commercial, and agricultural settings wherever a large-diameter coarse-thread fastener with a square head is required. The 7\/8-9 UNC thread is a standard coarse unified thread designation, making hardware and nut sourcing straightforward. Common applications include timber framing connections, heavy equipment mounting, and structural steel assemblies. The uncoated finish is appropriate for indoor or dry-environment use, or where a coating will be applied in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSquare head profile for high-torque wrench engagement, including pipe wrench use\u003c\/li\u003e\n\u003cli\u003e7\/8-9 UNC coarse thread for reliable engagement with standard heavy-duty nuts\u003c\/li\u003e\n\u003cli\u003e3-1\/2 inch length under head for medium-depth fastening applications\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets general-purpose structural fastening requirements\u003c\/li\u003e\n\u003cli\u003eUncoated finish suits dry-environment installations or field-coated assemblies\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener compatible with any application requiring a 7\/8-9 UNC square head bolt per ANSI\/ASME B18.2.1 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a qualified tradesperson using a wrench, pipe wrench, or adjustable wrench sized for the square head.
