It features a 1\/4-20 UNC thread and measures 1-1\/2 inches in overall length. The flat head profile sits flush with or below the surface of the mating material, making it a standard choice when a low-profile fastener is required. Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, this screw suits a wide range of light- to medium-duty mechanical and structural applications. Installation requires a standard slotted flathead screwdriver or bit.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in residential and light commercial maintenance, equipment assembly, panel mounting, and general fabrication work. The 1\/4-20 UNC thread is one of the most common inch-series thread sizes, making this fastener compatible with a broad range of tapped holes, threaded inserts, and standard hex nuts. It is appropriate for HVAC panel assembly, electrical enclosure work, plumbing fixture mounting, and similar trade-service tasks where a flush-seated fastener is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard tapped holes and hardware\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch overall length with full thread engagement along the shank\u003c\/li\u003e\n  \u003cli\u003eFlat head profile seats flush with the work surface\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flathead screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction with zinc finish for light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eNo washer — installs directly against the mating surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC machine screw suitable for use with any 1\/4-20 tapped hole, threaded insert, or matching nut in general mechanical and trade assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a standard slotted flathead screwdriver or power driver bit sized for the slot.
