The slotted drive accepts a standard flat-blade screwdriver. Constructed from alloy steel with a zinc-plated finish, this screw resists corrosion while providing the tensile strength needed in structural and equipment assemblies. Length is measured under the head. These screws are sold in a box of 100 and are a standard choice for maintenance technicians, contractors, and fabricators working with inch-series hardware.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in light to medium-duty mechanical assemblies, panel mounting, equipment maintenance, and general fastening tasks across HVAC, electrical, plumbing, and industrial service applications. The UNC (Unified National Coarse) thread form is compatible with standard tapped holes and hex nuts sized for 5\/16-18 thread. The round head profile provides a low-profile bearing surface without requiring a countersink or flat washer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for compatibility with standard inch-series tapped holes and hardware\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch length under head for consistent fastening depth\u003c\/li\u003e\n  \u003cli\u003eRound head profile with slotted drive for flat-blade screwdriver installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for higher tensile strength compared to low-carbon steel fasteners\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in general indoor and light-duty environments\u003c\/li\u003e\n  \u003cli\u003eBox of 100 screws sold as a single package unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 5\/16-18 UNC tapped holes or with matching hex nuts and threaded inserts in inch-series fastening applications across mechanical, electrical, and HVAC equipment assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation does not require specialized tools beyond a flat-blade screwdriver or appropriate socket driver.
