Manufactured from Grade 2 steel with a zinc plating finish, this screw resists corrosion and meets standard fastener requirements for light-to-medium mechanical assemblies. The pan head profile offers a low-profile, broad bearing surface suitable for thin panels and sheet metal applications. This box contains 100 screws, making it appropriate for production runs, maintenance kits, and service stock. Installation does not require washers, as the pan head geometry provides adequate clamping surface on most substrates.\u003c\/p\u003e\n\u003cp\u003eThis fastener is commonly used in electrical enclosures, HVAC control panels, light fixtures, and general mechanical assemblies where a 4-40 threaded hole is specified. The Phillips drive is compatible with standard screwdrivers and powered drivers, making it practical for repetitive fastening tasks in panel or cabinet assembly. The zinc plating provides moderate corrosion resistance suitable for indoor and sheltered installations. Trade electricians, HVAC technicians, and mechanical assemblers regularly use fasteners of this type during control board mounting, panel assembly, and equipment service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread size for compatibility with standard 4-40 tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch length under head for consistent engagement depth in standard panel stock\u003c\/li\u003e\n  \u003cli\u003ePan head profile provides a broad clamping surface without requiring a washer\u003c\/li\u003e\n  \u003cli\u003ePhillips drive accepts standard Phillips screwdrivers and power bits\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets general-purpose fastener strength requirements\u003c\/li\u003e\n  \u003cli\u003eZinc plating finish adds corrosion resistance for indoor mechanical environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose 4-40 UNC machine screw suitable for standard tapped holes requiring a pan head Phillips fastener in steel or thermoplastic assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a Phillips screwdriver or power driver with the appropriate bit size to avoid cam-out and fastener damage. Power down all electrical equipment before fastening or removing screws in control panels or enclosures. Do not overtighten into thermoplastic or soft materials, as Grade 2 steel can strip tapped holes under excessive torque. Follow applicable NEC or equipment manufacturer guidelines when installing fasteners in electrical assemblies.\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\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/8 inches\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\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\u003ePackage Weight\u003c\/strong\u003e: 1 pound\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: MPPI0-400620-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699049791794,"sku":"MPPI0-400620-100BX","price":450.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57b56f8876fa1608d841ca7231ea8b05.jpg?v=1788371679","url":"https:\/\/voomisupply.com\/products\/value-collection-mppi0-400620-100bx-4-40-x-5-8-in-pan-head-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
