The flat head profile sits flush with the mating surface when fully driven, making it a common choice in panels, brackets, and enclosures where a low-profile fastener is required. The UNC (Unified National Coarse) thread form engages quickly and is widely compatible with standard tapped holes. This screw is sized without a washer and is measured overall, meaning the 2.5-inch dimension includes the head. Installation is handled by general contractors, maintenance technicians, electricians, and HVAC service professionals alike.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for light-duty to medium-duty mechanical assemblies in residential and commercial applications. Typical uses include securing electrical enclosure panels, mounting brackets, HVAC cabinet components, and general sheet metal or structural assembly work where a coarse-thread zinc-plated steel screw meets the load and corrosion-resistance requirements. The slotted drive accepts a standard flat-blade screwdriver or bit. These screws are sold as a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC coarse thread for fast engagement with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eFlat head profile seats flush with the work surface when countersunk\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides basic corrosion resistance for indoor and sheltered applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose light-to-medium duty fastening\u003c\/li\u003e\n  \u003cli\u003eNo washer style — clean, compact install without additional hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose 1\/4-20 UNC machine screw for use in any application requiring a flat head slotted fastener with a 2.5-inch overall length in a standard coarse-thread tapped hole or with a matching nut.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eUse a properly sized flat-blade screwdriver or bit to avoid cam-out and head damage.
