Manufactured from Grade 2 steel with a zinc-plated finish, this fastener measures 5\/16-18 thread size with a 3\/4-inch length under the head. The UNC thread standard ensures broad compatibility with standard tapped holes and hex nuts. The zinc coating provides basic corrosion resistance suitable for indoor and light-duty applications. A 1\/2-inch hex key size makes installation straightforward with standard hand or power tools.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light to medium load fastening tasks encountered in trade work — securing equipment panels, mounting brackets, junction boxes, HVAC access doors, and plumbing fixture supports. The fully threaded shank provides maximum thread engagement across the full length, making it a reliable choice when clamping thin materials or assembling components where full thread contact is needed. It follows the Inch system of measurement and UNC threading, the most common standard found in North American trade equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement across the entire 3\/4-inch length\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose, light to medium duty fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance for indoor and sheltered environments\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard compatible with standard North American tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive for use with common hand wrenches, sockets, or power drivers\u003c\/li\u003e\n  \u003cli\u003eSold individually; minimum order quantity of 100 units\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 cap screw for use wherever Grade 2 steel fasteners with zinc plating are specified in general mechanical, HVAC, plumbing, or electrical assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 1\/2-inch wrench, socket, or hex driver. Ensure the mating tapped hole or nut meets the 5\/16-18 UNC thread standard before driving.
