It features a 3\/8-16 UNC thread and a length under head of 2.75 inches. The square head profile provides a larger bearing surface and allows for wrench engagement in tight spaces where a hex head cannot be used. This bolt is a common fastener in structural assemblies, equipment mounting, and general industrial applications. Installation is typically performed by maintenance technicians, millwrights, or tradespeople using a box or open-end wrench sized for the square head geometry.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for use in light-duty structural connections, equipment frames, conveyor systems, wood-to-metal connections, and general fabrication work. The Grade 2 steel designation indicates a low-carbon, unalloyed steel suitable for non-critical fastening applications that do not require high-tensile or hardened hardware. It is commonly used wherever a traditional square head profile is called for by design or legacy equipment specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for standard coarse-thread engagement\u003c\/li\u003e\n  \u003cli\u003e2.75 inches length under head for moderate clamping depth\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows wrench access in confined or irregular mounting locations\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose, non-critical fastening\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; compatible with field-applied coatings or use in dry interior environments\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose square head fastener for use in light structural, fabrication, and equipment assembly applications requiring a 3\/8-16 UNC coarse-thread bolt with a square head profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a wrench or socket sized to the square head.
