Manufactured from Grade 2 steel with a zinc finish, this screw measures 3\/16 inches in overall length. It is a standard inch-system fastener used across a wide range of light-duty mechanical assembly applications. Electricians, HVAC technicians, and general tradespeople reach for this size when securing small panels, terminal covers, enclosure hardware, and instrument mounting brackets.\u003c\/p\u003e\n\u003cp\u003eThis 4-40 flat head slotted screw is suited for residential and commercial applications wherever a flush-seating fastener is required in a tapped hole or threaded insert. The flat head countersinks into the workpiece, producing a smooth, low-profile finish. Common install scenarios include control board mounting, junction box cover attachment, and small-gauge sheet metal or plastic panel assembly. The zinc finish provides basic corrosion resistance for indoor and protected environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread form for compatibility with standard inch-system tapped holes and inserts\u003c\/li\u003e\n  \u003cli\u003eFlat head profile countersinks flush with the workpiece surface\u003c\/li\u003e\n  \u003cli\u003eSlotted drive works with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for reliable light-duty mechanical hold\u003c\/li\u003e\n  \u003cli\u003eZinc finish for basic indoor corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBox quantity of 100 for stocking service vehicles and shop inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC machine screw for use in any application requiring a flat head slotted fastener in an inch-system tapped hole or threaded insert.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a flat-blade screwdriver sized to the slotted head to avoid cam-out and fastener damage.
