It conforms to ASME B18.6.3 and SAE J82 standards, ensuring dimensional accuracy and consistent performance. The pan head profile provides a low-profile bearing surface with a wide underside bearing area. The slotted drive is compatible with standard flat-blade screwdrivers. These screws are sold in minimum quantities of 100 per order and are suited for light-duty mechanical assemblies requiring a corrosion-resistant, standardized fastener.\u003c\/p\u003e\n\u003cp\u003eThese machine screws are used in a wide range of light mechanical and electrical assembly applications. Common installation environments include HVAC control panels, electrical enclosures, junction boxes, sheet metal assemblies, and general equipment maintenance tasks. The 4-40 thread size is a fine-pitch unified thread commonly found in instrumentation, small appliances, and low-voltage control wiring enclosures. Technicians in HVAC, electrical, and plumbing trades frequently keep 4-40 hardware on hand for panel and bracket fastening during service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 unified thread size for compatibility with standard tapped holes in light mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e1.25-inch length measured under head for accurate fit in stacked or layered materials\u003c\/li\u003e\n  \u003cli\u003ePan head profile distributes clamping load across a broad bearing surface\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers for quick installation\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel finish provides corrosion resistance in dry indoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 machine screw for use in any application requiring ASME B18.6.3 compliant slotted pan head fasteners in the inch measurement system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand or with a standard flat-blade screwdriver sized to the slotted head. Always ensure the mating threaded hole or nut is properly tapped to 4-40 specification before driving the fastener to avoid thread stripping. Power down any electrical equipment or control panel before fastening hardware in live enclosures, in accordance with NEC lockout and tagout procedures. Do not overtighten in thin sheet metal applications where thread engagement may be limited.\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: 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: 1.25 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 Coating\u003c\/strong\u003e: Zinc-Plated\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\u003ePackage Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: MSPI0-401250-100B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723078959410,"sku":"MSPI0-401250-100B","price":1217.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/636f8dc39735e432bac9c2c164faa596.jpg?v=1788600296","url":"https:\/\/voomisupply.com\/products\/value-collection-mspi0-401250-100b-4-40-pan-head-slotted-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
