Manufactured from Grade 5 steel with an uncoated finish, this bolt features a 3\/4-10 UNC thread size and a 3-inch length under head. The square head profile provides four flat bearing surfaces, making it well-suited for applications where the fastener head must be held stationary during tightening or where the bolt must be driven into wood or soft materials to resist rotation. Typically installed by millwrights, ironworkers, pipefitters, and general contractors across structural and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in general industrial, structural, and mechanical construction applications where a coarse-thread fastener with a non-round head is specified. Common install scenarios include timber framing, machine mounting, rail and track work, and agricultural or heavy equipment assembly where a wrench-flat head style is preferred over a hex configuration. The uncoated steel finish is suited for dry or interior environments or applications where the installer will apply a field coating after assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSquare head profile allows four-point wrench engagement and resists rotation during installation\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC coarse thread for strong thread engagement in steel, iron, and structural applications\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head accommodates moderate material stack-ups in structural assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction provides minimum tensile strength suitable for general structural fastening\u003c\/li\u003e\n  \u003cli\u003eUncoated finish for dry or protected environments, or for field coating after installation\u003c\/li\u003e\n  \u003cli\u003eManufactured to ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fastener for structural and mechanical assemblies requiring a 3\/4-10 UNC square head bolt with a 3-inch length under head per ANSI\/ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, ironworkers, or general contractors using an adjustable or box-end wrench sized for 3\/4-inch square head bolts. Always ensure mating nut and washer specifications match the bolt grade and thread standard before assembly. De-energize and lock out any machinery before fastening into live equipment.
