Manufactured from alloy steel with a zinc finish for basic corrosion resistance, this screw features a slotted drive and Unified National Coarse (UNC) thread form. The round head profile sits above the work surface without countersinking, making it suitable for through-fastening where a low-profile head is not required. Installers and technicians across HVAC, electrical, plumbing, and general mechanical disciplines reach for this fastener when a standard UNC thread pitch and slotted drive are specified.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for residential and light commercial mechanical assemblies, equipment panels, junction boxes, and structural brackets where a 5\/16-18 UNC thread is called out. The zinc finish provides a measure of protection in dry or mildly humid indoor environments. The 2-1\/4 inch length under head accommodates moderate material stack-up without bottoming out in standard threaded holes or nuts. Sold in multiples of 100, this SKU is appropriate for shop stock, service van inventory, or project-quantity procurement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n  \u003cli\u003e2-1\/4 inch length under head suits moderate material stack-up\u003c\/li\u003e\n  \u003cli\u003eRound head profile requires no countersink preparation\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for strength in mechanical fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides basic corrosion resistance in dry indoor environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC machine screw suitable for use in any application calling for a 5\/16-18 thread, round head, and slotted drive in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand or with a standard flat-blade screwdriver or slotted bit driver. Verify the mating thread is 5\/16-18 UNC before installation to avoid cross-threading. Power down or de-energize equipment before fastening near electrical components per applicable NEC guidelines.
