Manufactured from Grade 2 steel with a zinc-plated finish, this fastener resists corrosion in light-duty indoor and outdoor applications. The partially threaded shank provides a smooth bearing surface under the head, which helps align mating components and reduce stress concentration. At 0.07 pounds per piece, this screw is suited for light to medium load applications where a standard UNC thread profile is specified. Installation requires a 1\/2-inch hex key or wrench.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used across a wide range of trade and maintenance applications including HVAC equipment frames, electrical panel mounting, plumbing fixture brackets, and general sheet metal or structural steel assemblies. The UNC thread standard and inch-system dimensions make it compatible with standard tapped holes and nuts in imperial-spec equipment. Licensed tradespeople and maintenance technicians working on commercial or residential mechanical systems will encounter this fastener type regularly as an OEM or service replacement fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for compatibility with standard imperial tapped holes and hardware\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading for clean shank engagement\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose structural fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides light corrosion resistance in typical service environments\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive for installation with standard wrenches or sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose imperial fastener for use in any application requiring a 5\/16-18 UNC hex head cap screw with a 3-inch length under head and partial threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 1\/2-inch wrench, socket, or hex driver.
