It features a round head profile with a slotted drive and measures 3\/16 inches in length under the head. Manufactured from steel with a zinc finish, this screw meets ASME B18.6.3 and SAE J82 standards, making it a reliable choice for precision fastening in instrumentation, electrical enclosures, small appliances, and light mechanical equipment. Installation is straightforward with a standard flathead screwdriver. These screws are sold in multiples of 100, with a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for residential and commercial applications where a small-diameter, fine-thread fastener is required. Common use cases include securing panels, terminal covers, electrical components, and similar assemblies where a 5-40 thread form is specified. The slotted round head sits flush-proud against the mating surface without requiring a countersunk hole, making it a practical choice for thin-gauge sheet metal, plastic housings, and PCB mounting brackets used by electricians, HVAC technicians, and general equipment assemblers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 thread size provides a fine-pitch engagement suitable for thin materials and precision assemblies\u003c\/li\u003e\n  \u003cli\u003eRound head profile distributes clamping load over a wider bearing surface without countersinking\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flathead screwdrivers for quick installation and removal\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish offers corrosion resistance in typical indoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 standards for dimensional and mechanical consistency\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 100 to support production and service stock requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-purpose fastener for any assembly specifying a 5-40 slotted round head machine screw per ASME B18.6.3 or SAE J82.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard flathead screwdriver sized to match the slotted head. Always verify thread engagement depth in the mating component before applying torque to avoid stripping the 5-40 thread form.
