This fully threaded bolt features a 5\/16-18 UNC thread and a 1-1\/2 inch length under head, providing consistent clamping force across its full shank length. The integrated smooth flange distributes load evenly against the mating surface, reducing the need for a separate washer. Manufactured from alloy steel with a material grade rating of 170M PSI and meeting ASTM A574 standards, this bolt is built for demanding industrial and trade applications. Installation is performed using a 12-point drive with a 5\/16 inch drive size.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for use in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, and general mechanical fastening where a high-strength, fully threaded flange bolt is required. The smooth flange profile makes it appropriate for applications where the flange must seat flush without marring softer mating surfaces. It is commonly installed by maintenance technicians, millwrights, and trade professionals working on light-to-medium duty assemblies requiring precise thread engagement and load distribution.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC shank for maximum thread engagement along the full 1-1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003eSmooth flange with 15\/32 inch (0.457 to 0.469 inches) diameter distributes clamping load without a separate washer\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated at 170M PSI for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A574 standard for socket head cap screws and high-strength fasteners\u003c\/li\u003e\n  \u003cli\u003e12-point drive design allows higher torque application in confined spaces\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for dry or controlled-environment installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener for assemblies requiring a 5\/16-18 UNC fully threaded smooth flange bolt meeting ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 12-point socket or bit in the 5\/16 inch drive size.
