It features a round head profile and a Phillips drive, allowing installation with standard Phillips screwdrivers or bits. The screw is manufactured from steel with a zinc finish that provides basic corrosion resistance for indoor and sheltered applications. At 1\/4 inch length under head, this fastener suits thin-panel and close-tolerance assemblies. It conforms to ASME B18.6.3 and SAE J82 standards. Installation is typically performed by mechanical assemblers, maintenance technicians, or electricians working on panel-mounted hardware and light electrical enclosures.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for residential and commercial applications where a small-diameter, fine-pitch machine screw is required. Typical use cases include securing terminal blocks, small enclosure panels, electronic housings, control box covers, and similar sheet-metal or thin-material assemblies. The 4-40 thread size is a common standard in electrical and HVAC control panel work. Sold individually in package quantity of 1, with a minimum order quantity of 100 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 unified coarse thread for reliable engagement in tapped holes and threaded inserts\u003c\/li\u003e\n  \u003cli\u003eRound head profile provides a low-profile, smooth bearing surface\u003c\/li\u003e\n  \u003cli\u003ePhillips drive compatible with standard Phillips No. 1 bits and screwdrivers\u003c\/li\u003e\n  \u003cli\u003eZinc finish offers basic corrosion resistance for indoor and protected environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eNo washer included; designed for direct head-to-surface clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 machine screw replacement or new-installation fastener for applications requiring an ASME B18.6.3 and SAE J82 compliant round-head Phillips screw in a 1\/4 inch under-head length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a Phillips No. 1 screwdriver or bit. Verify the mating hole is properly tapped to 4-40 specifications before driving to avoid cross-threading. Do not overtighten; small-diameter machine screws are susceptible to thread stripping in soft materials. Ensure the assembly is de-energized before fastening screws in live electrical enclosures, per applicable NEC guidelines.\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: Round\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\/4 inch\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: J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3; SAE J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00098 pounds\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: 0404MPR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717660901682,"sku":"0404MPR","price":572.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d6095d47b08d8a84babf458679c0de9.jpg?v=1788544037","url":"https:\/\/voomisupply.com\/products\/value-collection-0404mpr-4-40-x-1-4-in-round-head-phillips-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
