Designed for use in threaded assemblies requiring a flush or countersunk fastening surface, this screw features unified national coarse (UNC) thread form. The flat head profile seats flush with or below the mating surface when installed in a properly countersunk hole. At 3 inches overall length, it suits deeper material stacks or standoff applications common in mechanical, HVAC panel, and electrical enclosure work. Sold in a pack of 25 units.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for light industrial, commercial, and residential trade applications where corrosion resistance is required. Grade 18-8 stainless steel provides good resistance to rust and oxidation, making it appropriate for indoor and moderately exposed outdoor environments. HVAC technicians, electricians, and plumbers commonly use this screw type when assembling equipment panels, brackets, junction boxes, and access doors. The Phillips drive accepts standard and power-drive bits, simplifying installation in tight spaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread form for compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n\u003cli\u003e3 inch overall length suits deeper material stack assemblies\u003c\/li\u003e\n\u003cli\u003eFlat head profile allows flush or countersunk seating\u003c\/li\u003e\n\u003cli\u003eGrade 18-8 stainless steel construction resists corrosion and oxidation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish with no plating to interfere with conductive grounding paths\u003c\/li\u003e\n\u003cli\u003ePhillips drive accepts standard bits for hand or power installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 UNC machine screw for use with any tapped hole, threaded insert, or nut conforming to 1\/4-20 unified national coarse thread specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of machine screws in equipment panels and enclosures should be performed with power off and stored energy discharged per applicable NEC or equipment-specific lockout\/tagout procedures. Ensure the receiving hole is properly countersunk to the flat head angle before driving to avoid surface distortion. Use a correctly sized Phillips bit to prevent cam-out and fastener head damage.
