Built from Grade 2 steel with a zinc plating finish, this screw offers basic corrosion resistance suitable for indoor and light-duty applications. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, keeping the assembly low-profile. The Phillips drive is compatible with standard screwdrivers and power drivers. These screws are sold in a box quantity of 100 units, making them practical for production assembly, maintenance stock, or field kit replenishment.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light mechanical assemblies, electronics enclosures, panel mounting, and equipment maintenance tasks where a 4-40 UNC thread and flush-mount fastener are specified. The 3\/8 inch overall length is measured end-to-end, with the full 3\/8 inch also serving as the length under head, confirming the flat-head geometry. Typical users include electricians, HVAC technicians, and general maintenance professionals who need small-diameter machine screws for control board brackets, access panels, and enclosure hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread for compatibility with standard tapped holes in that size\u003c\/li\u003e\n  \u003cli\u003eFlat head profile allows flush or countersunk installation\u003c\/li\u003e\n  \u003cli\u003ePhillips drive works with common screwdrivers and bit drivers\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for light-duty fastening\u003c\/li\u003e\n  \u003cli\u003eZinc plating adds basic corrosion resistance for indoor use\u003c\/li\u003e\n  \u003cli\u003eSold in a 100-piece box quantity for bench stock and production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC flat head Phillips machine screw for use in any application requiring that thread size and head style in inch-system assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand or with a Phillips screwdriver or bit driver. Ensure the mating component has a properly tapped 4-40 UNC hole or a matching threaded insert before driving the screw. For flush seating, the receiving surface should be countersunk to match the flat head angle. Do not overtighten; Grade 2 fasteners have lower proof load ratings than higher-grade hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Phillips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces per box\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound (package)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MPFI0-400370-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720162771250,"sku":"MPFI0-400370-100BX","price":766.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44088048730e2620a2c8cc6a30f59bae.jpg?v=1788561192","url":"https:\/\/voomisupply.com\/products\/value-collection-mpfi0-400370-100bx-4-40-flat-head-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
