This fastener follows ASME B18.6.3 and SAE J82 standards, making it a reliable choice for general-purpose mechanical assemblies. The pan head profile provides a low-profile, wide bearing surface suitable for sheet metal, light structural, and equipment enclosure applications. The zinc coating offers basic corrosion resistance in dry indoor environments. Length is measured under the head, giving a full 1 inch of thread engagement depth when fully seated.\u003c\/p\u003e\u003cp\u003eThis screw is used in light-duty mechanical and electrical assembly work, including control panel fabrication, enclosure mounting, and small equipment construction. The 4-40 thread size is commonly found in instrumentation, electronic hardware, and HVAC control board mounting. It is appropriate for residential and commercial applications where a small-diameter, unified inch-thread fastener is required. Installers typically use these in quantity for repetitive fastening tasks in panel shops, field service, and bench assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 unified inch thread for standard small-fastener applications\u003c\/li\u003e\n\u003cli\u003ePan head profile with wide bearing surface and low profile\u003c\/li\u003e\n\u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.6.3 and SAE J82 dimensional and material standards\u003c\/li\u003e\n\u003cli\u003eLength measured under head for accurate thread engagement planning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 x 1 inch pan head slotted machine screw per ASME B18.6.3, compatible with any application requiring a unified inch-thread 4-40 fastener in this head style and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a flat-blade screwdriver sized to the slotted head. Ensure the mating threaded hole or nut is tapped to 4-40 specification before driving. Do not overtighten, as the small thread diameter is susceptible to stripping under excessive torque. Power down any electrical equipment before fastening hardware within live enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Pan Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\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: 0416MSP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693384794418,"sku":"0416MSP","price":394.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed7abfcabd9792e56f7fe6bd11b3843e.jpg?v=1788311544","url":"https:\/\/voomisupply.com\/products\/value-collection-0416msp-4-40x1-pan-head-slotted-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
