It features a flat undercut head with a No. 1 Phillips drive and a Type F point, which cuts its own mating thread on installation. The screw is manufactured from AISI 1016-1024 steel and finished with a zinc plating for basic corrosion resistance. Overall length is 0.25 inches. Electricians, HVAC technicians, and sheet metal workers use this screw type when assembling control panels, enclosures, and light-gauge metal components where a flush or near-flush head profile is required.\u003c\/p\u003e\u003cp\u003eThis screw is suited for light-gauge metal assembly work in residential and commercial applications. Typical uses include securing cover plates, terminal strips, and small brackets inside electrical enclosures, HVAC control boards, and sheet metal assemblies. The flat undercut head sits close to the work surface, reducing protrusion in tight-clearance assemblies. It is sold in multiples of 100 units per order, with a package quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread size with Type F thread cutting point — no tap required in ductile metals\u003c\/li\u003e\n\u003cli\u003eFlat undercut head profile keeps fastener flush in tight-clearance assemblies\u003c\/li\u003e\n\u003cli\u003eNo. 1 Phillips drive for compatibility with standard power and hand drivers\u003c\/li\u003e\n\u003cli\u003eAISI 1016-1024 steel construction meets ASME B18.6.3, ASME B18.6.4, and SAE J933 standards\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic oxidation resistance for indoor use\u003c\/li\u003e\n\u003cli\u003e0.25 inch overall length suited for thin-gauge metal applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 UNC thread cutting screw for use in light-gauge metal panels, enclosures, and assemblies where a self-threading flat undercut head fastener is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians, HVAC technicians, or sheet metal workers using a No. 1 Phillips screwdriver or power driver. Always de-energize electrical enclosures and follow NFPA 70 (NEC) lockout\/tagout procedures before working inside panels. Use the correct pilot hole diameter for the base material to ensure proper thread engagement and avoid stripping. Do not overtighten — thread cutting screws in light-gauge metal can strip if torque is not controlled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat Undercut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: No. 1 Phillips\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: AISI 1016-1024 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0006 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.6.3, ASME B18.6.4, SAE J933\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 0404FPU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721447145778,"sku":"0404FPU","price":1520.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/835415a0b2fc506d107b8580ff705c7f.jpg?v=1788577531","url":"https:\/\/voomisupply.com\/products\/value-collection-0404fpu-4-40-unc-thread-cutting-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
