Conforming to ASME B18.6.3 and SAE J82 material grade standards, this fastener is suited for general-purpose mechanical assembly applications requiring a compact, corrosion-resistant threaded fastener. The round head profile provides a low-profile bearing surface, and the Phillips drive allows for quick installation with standard tooling. Sold in multiples of 50, this screw is appropriate for production assembly, maintenance, and repair tasks across a range of light-duty mechanical and electrical enclosure applications.\u003c\/p\u003e\u003cp\u003eThis machine screw is used in residential and commercial assembly environments where 4-40 threaded connections are specified. Typical applications include securing panels, brackets, and light-duty components in electrical enclosures, control boxes, and mechanical subassemblies. It is installed by electricians, HVAC technicians, and general maintenance professionals who require a standardized inch-series threaded fastener with a Phillips drive interface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 thread size, inch-series, for standard light-duty mechanical fastening\u003c\/li\u003e\n\u003cli\u003e1 inch length measured under the head per ASME B18.6.3\u003c\/li\u003e\n\u003cli\u003eRound head profile with Phillips drive for use with common screwdrivers and power drivers\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.6.3 and SAE J82 standards for dimensional and material conformance\u003c\/li\u003e\n\u003cli\u003eSold in minimum order quantities of 50 units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose inch-series machine screw for applications specifying a 4-40 thread, 1 inch length under head, round head, and Phillips drive configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a Phillips screwdriver or a power driver fitted with the appropriate Phillips bit. Ensure the mating tapped hole or nut matches the 4-40 thread specification before installation. De-energize any electrical equipment before securing fasteners in or around live panels or enclosures. Do not overtighten, as the small thread diameter of a 4-40 fastener is susceptible to thread stripping in softer base materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 (Inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: J82\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\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: MPRI0-401250-100T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693702906162,"sku":"MPRI0-401250-100T","price":24.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_39a94fd0-dd50-4890-a8f0-93389f2a90e4.jpg?v=1788316301","url":"https:\/\/voomisupply.com\/products\/value-collection-mpri0-401250-100t-4-40-x-1-in-round-head-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
