The bolt features a 3\/8-16 UNC thread profile, a fully threaded shank measuring 1-1\/4 inches under the head, and a smooth flange diameter of 13\/16 inches (0.8125 inches). Manufactured from Grade 8 alloy steel to SAE J429 specifications, this bolt is suited for demanding mechanical and structural assemblies. The uncoated finish leaves the fastener ready for use or field-applied coating as required by the application. Drive type is hex for standard wrench and socket tooling.\u003c\/p\u003e\n\u003cp\u003eThis bolt is a practical choice for mechanical assemblies, equipment mounting, and structural connections that require a UNC thread form in a 3\/8-inch diameter. The smooth flange face seats cleanly against mating surfaces without marring, making it appropriate for use in HVAC equipment frames, pump and blower housings, panel mounting, and similar trade installations where vibration resistance and consistent clamp load matter. Sold in a package quantity of 25.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction meets SAE J429 mechanical requirements for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form is fully threaded along the 1-1\/4-inch shank length under head\u003c\/li\u003e\n  \u003cli\u003eSmooth flange diameter of 13\/16 inches integrates a bearing surface, eliminating the need for a separate flat washer\u003c\/li\u003e\n  \u003cli\u003eHex drive is compatible with standard open-end, box, and socket wrenches\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for dry or protected installations or field coating\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 25 for bench stock and service van inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC smooth flange bolt for use in any application requiring SAE J429 Grade 8 alloy steel hex-drive fasteners with an integrated flange bearing surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with standard hex wrenches or sockets sized for a 3\/8-inch fastener.
