Made from Grade 2 steel with an uncoated finish, this fastener is designed for general-purpose mechanical and structural applications. The square head profile allows wrench engagement on all four sides, which is useful in tight clearances or when a standard hex head is not practical. This bolt meets ANSI\/ASME B18.2.1 dimensional standards. It is commonly installed by maintenance technicians, millwrights, plumbers, and HVAC service professionals working on equipment frames, brackets, and supports.\u003c\/p\u003e\n\u003cp\u003eSquare head bolts of this size are used in a wide range of light commercial and residential mechanical installations. Typical applications include equipment mounting, pipe support assemblies, ductwork framing, and general structural connections where a through-bolt or machine-threaded fastener is required. The 5\/16-18 UNC coarse thread provides reliable engagement in standard tapped holes or with a matching nut. Minimum order quantity is 100 pieces, sold as a single package unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped hardware\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch length under head suits medium-depth clamping and through-bolt applications\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows four-sided wrench engagement in confined spaces\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for general-purpose mechanical use\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for dry or protected indoor installations\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 compatible with any standard 5\/16-18 UNC tapped hole or matching nut in mechanical, structural, and equipment-mounting applications.\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.
