Manufactured from Grade 2 steel with a zinc-plated finish, this fastener measures 7\/16 inches in overall length and is sized without a washer flange. The flat head profile sits flush with the mating surface when fully driven, making it well suited for applications where a low-profile or countersunk finish is required. This screw meets ANSI B 18.6.7 M, DIN 963, ISO 2009, and JIS B 1101 standards. It is packaged in a box of 100 pieces and installed by electricians, HVAC technicians, and general maintenance trades in light-duty panel and enclosure work.\u003c\/p\u003e\n\u003cp\u003eThis fastener is commonly used in light-gauge metal panels, electrical enclosures, junction boxes, instrument housings, and equipment assemblies where a 4-40 thread form is specified. The zinc plating provides baseline corrosion resistance suitable for indoor and light-duty applications. The slotted drive accommodates standard flat-blade screwdrivers, which are a common hand tool in panel and control board service work. The 7\/16-inch overall length is measured from the top of the flat head to the tip of the thread.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 unified coarse thread, 7\/16 inches overall length\u003c\/li\u003e\n  \u003cli\u003eFlat head profile for flush or countersunk installations\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B 18.6.7 M, DIN 963, ISO 2009, and JIS B 1101 standards\u003c\/li\u003e\n  \u003cli\u003eSold in a box of 100 pieces to support production and service quantities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 flat head slotted machine screw suitable for use in electrical panels, control enclosures, instrument housings, and light-gauge metal assemblies requiring a flush-seat fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard flat-blade screwdriver sized to the slotted head. De-energize all electrical equipment before driving or removing fasteners in live panels or enclosures, following applicable NEC requirements. Avoid overtightening in light-gauge or tapped plastic mating parts to prevent thread stripping. Use a countersink of the appropriate angle to ensure full flat-head contact with the mating surface.\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\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: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 7\/16 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 Coating\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\u003eFastener Standards\u003c\/strong\u003e: ANSI B 18.6.7 M, DIN 963, ISO 2009, JIS B 1101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\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: MSFI0-400430-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714439315762,"sku":"MSFI0-400430-100BX","price":1968.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fafb121d5b39b19045c1a84489aa1531.jpg?v=1788501477","url":"https:\/\/voomisupply.com\/products\/value-collection-msfi0-400430-100bx-4-40-flat-head-slotted-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
