Built to Grade 2 specification and certified to ASTM A307, this bolt features a 5\/16-18 UNC thread and measures 1-1\/4 inches in length under the head. The hot-dipped galvanized finish provides corrosion resistance suited for outdoor, wet, or exposed environments. Sold in a minimum order quantity of 100 pieces, this bolt is a practical bulk fastener choice for contractors, maintenance crews, and tradespeople who need a reliable, code-referenced fastener on hand in volume.\u003c\/p\u003e\n\u003cp\u003eThis bolt is appropriate for light to medium-duty structural connections, equipment mounting, framing hardware, brackets, and general mechanical assemblies where a standard Grade 2 galvanized fastener is specified. The 5\/16-18 UNC thread is one of the most commonly called-out sizes across HVAC equipment panels, electrical enclosures, plumbing supports, and pool equipment frames. Fully threaded construction allows fastening across the full length of the bolt, which is useful in thin-material or through-bolt applications where partial threading would leave an unengaged shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread — one of the most widely used standard thread sizes in trade applications\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head for compatibility with thin to medium material stacks\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement across the bolt length\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in outdoor and wet environments\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction certified to ASTM A307 for general structural use\u003c\/li\u003e\n  \u003cli\u003eSold in 100-piece increments for jobsite and shop stock replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC fully threaded hex head bolt suitable for use wherever Grade 2 galvanized fasteners are specified in light structural, mechanical, or utility installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with an appropriate hex wrench or socket driver sized for a standard 5\/16-inch hex head bolt.
