It features unified national coarse (UNC) threading along the full 3-inch overall length with no washer. The flat head profile sits flush with or below the mating surface, making it a standard choice for countersunk applications. The slotted drive accepts a flat-blade screwdriver. This fastener is used across a broad range of mechanical assembly, maintenance, and equipment installation tasks in HVAC, electrical, plumbing, and general trade work.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light- to medium-duty fastening applications where a flush or countersunk head is required. Typical installations include panel mounting, equipment enclosures, brackets, and structural assemblies using standard inch-series hardware. The zinc finish provides basic corrosion resistance for indoor and protected outdoor environments. Trade professionals in HVAC, electrical, and mechanical service regularly stock this fastener size for general maintenance and equipment assembly tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e3-inch overall length with full-length threading\u003c\/li\u003e\n  \u003cli\u003eFlat head profile allows flush or countersunk seating\u003c\/li\u003e\n  \u003cli\u003eSlotted drive for flat-blade screwdriver installation\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction with zinc finish for basic corrosion protection\u003c\/li\u003e\n  \u003cli\u003eNo washer style — clean, direct bearing surface against the mating material\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1\/4-20 UNC inch-series machine screw with a flat countersunk head and slotted drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a flat-blade screwdriver sized to the slotted head.
