The round head profile with Phillips drive provides a low-profile clamping surface and straightforward installation with standard tooling. Manufactured from steel with a zinc finish for basic corrosion resistance, this screw meets ASME B18.6.3 and SAE J82 dimensional and material standards. The 1.25-inch length under head is suited for securing thin panels, terminal strips, and chassis components where a smaller thread pitch offers reliable engagement in tapped holes or with mating nuts.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for residential and commercial electrical, HVAC control panel, and light-duty mechanical assembly environments. The 4-40 thread size is common in control boards, junction box hardware, fan blade brackets, and instrument housings across HVAC, refrigeration, and electrical trades. The zinc finish provides a measure of protection against mild atmospheric corrosion, making it suitable for indoor and sheltered installations. This SKU is sold as a minimum order quantity of 100 pieces per order, making it practical for bench stock and service van inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread size for compatibility with standard tapped holes and 4-40 hex nuts\u003c\/li\u003e\n  \u003cli\u003e1.25-inch length under head for moderate-depth fastening through panels and brackets\u003c\/li\u003e\n  \u003cli\u003eRound head with Phillips drive for use with standard Phillips screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eSteel construction to Grade J82 with zinc finish for strength and basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eNo washer style, reducing total installed height in tight clearance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC machine screw for use in any application requiring this thread size and head configuration; verify thread engagement depth and clearance before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand tool or power driver using a Phillips bit sized for a number 4 screw. Always verify the tapped hole or mating nut is the correct 4-40 thread specification before driving. Do not overtighten into soft materials such as aluminum or plastic, as the small thread diameter is susceptible to stripping. Power down any electrical equipment before fastening hardware inside enclosures or control panels.\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: 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: 1.25 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: 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 and 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\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 pounds\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: 0420MPR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718248694066,"sku":"0420MPR","price":2194.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a715e89928ba78c888f0bb55e61f8c52.jpg?v=1788551153","url":"https:\/\/voomisupply.com\/products\/value-collection-0420mpr-4-40-x-1-25-in-round-head-phillips-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
