It is manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance. The flat head profile sits flush with the mating surface when fully driven, making it a standard choice for assemblies where a smooth, low-profile fastener is required. The slotted drive is compatible with flat-blade screwdrivers and common bit sets. This screw uses Unified National Coarse (UNC) threading and is sold in a minimum order quantity of 100 units per transaction.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for general-purpose mechanical assembly in light industrial, maintenance, and fabrication applications. The 5\/16-18 UNC thread is one of the most common inch-series coarse thread sizes, fitting a wide range of tapped holes and standard hex nuts. Typical use cases include metal-to-metal fastening in enclosures, brackets, machinery panels, and structural assemblies where a countersunk flat head is required to maintain a flush surface finish. Installation is handled by mechanical assemblers, maintenance technicians, and tradespeople working across HVAC, electrical, and general mechanical disciplines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread — common coarse inch-series thread, compatible with standard tapped holes and nuts\u003c\/li\u003e\n\u003cli\u003e2-1\/4 inch overall length with full-length measurement under head also at 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003eFlat head profile provides flush-mount finish when countersunk\u003c\/li\u003e\n\u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers and bits\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction with zinc finish for general-purpose corrosion protection\u003c\/li\u003e\n\u003cli\u003eSold in multiples of 100 units — suitable for production and maintenance stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 5\/16-18 UNC tapped holes.
