The screw measures 1.25 inches in length under the head and is manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The pan head profile keeps a low, rounded silhouette, making it well suited for general mechanical assembly where clearance above the fastener is limited. These screws are installed without a washer. Electricians, HVAC technicians, panel builders, and general assembly technicians routinely use 4-40 Phillips machine screws to secure enclosures, terminal strips, and light-duty brackets.\u003c\/p\u003e\n\u003cp\u003eThis size and thread pattern is widely used in light-duty mechanical and electrical assemblies. The 4-40 UNC thread is a standard coarse-thread designation common in control panels, junction boxes, electronic enclosures, and small equipment housings. The zinc coating provides a functional level of corrosion protection suited for dry indoor environments. The box quantity of 100 units supports production-line use, service van stocking, and bench repair operations where fastener turnover is frequent.\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 control and enclosure hardware\u003c\/li\u003e\n  \u003cli\u003e1.25-inch length measured under the head for precise fit in layered assemblies\u003c\/li\u003e\n  \u003cli\u003ePan head profile provides a wide bearing surface without sharp edges\u003c\/li\u003e\n  \u003cli\u003ePhillips drive works with standard No. 1 Phillips screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction with zinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 100 for shop stocking and repeat-use applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 4-40 UNC threaded machine screw with a pan head and Phillips drive, including electrical enclosures, control panels, and light mechanical assemblies in indoor environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a No. 1 Phillips screwdriver or matching power-bit to avoid cam-out and fastener damage. Confirm the mating tapped hole or nut is 4-40 UNC thread before installation. De-energize any electrical enclosure or panel before inserting fasteners near live conductors, following applicable NEC requirements. Do not overtorque; Grade 2 steel has lower tensile strength than higher-grade alloys and the small thread cross-section is vulnerable to stripping.\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: Pan Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Phillips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.25 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\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0008 pounds (per screw)\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: MPPI0-401250-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702974972210,"sku":"MPPI0-401250-100BX","price":1843.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/146fcf81dd5149a9b27e8e2e8ba3869e.jpg?v=1788414148","url":"https:\/\/voomisupply.com\/products\/value-collection-mppi0-401250-100bx-4-40-pan-head-phillips-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
