It features a pan head profile with a slotted drive, allowing installation with a standard flat-blade screwdriver. The screw is manufactured from steel with a zinc finish that provides basic corrosion resistance. At 0.25 inches length under head, this fastener is suited for shallow through-hole or tapped-hole applications. It conforms to ASME B18.13a and SAE J82 standards, ensuring dimensional consistency across production and maintenance tasks. Maintenance technicians, assemblers, and trade professionals use this screw where a small-diameter, low-profile head fastener is required.\u003c\/p\u003e\u003cp\u003eThis machine screw is used in light mechanical assembly, control panel fabrication, enclosure hardware, and general equipment maintenance across HVAC, electrical, and related trades. The 4-40 thread size is common in instrument panels, junction boxes, and small component mounting. The pan head profile distributes clamping load evenly over flat or sheet metal surfaces. The slotted drive is compatible with standard manual and powered flat-blade tools. This screw ships in a minimum order quantity of 100 units, making it suitable for stocking in service vehicles or shop inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 unified coarse thread for use in standard tapped holes and inserts\u003c\/li\u003e\n\u003cli\u003ePan head profile provides a wide, low-profile bearing surface\u003c\/li\u003e\n\u003cli\u003eSlotted drive compatible with flat-blade screwdrivers and bits\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.13a and SAE J82 dimensional standards\u003c\/li\u003e\n\u003cli\u003eInternal tooth washer style for added locking capability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose 4-40 machine screw for use in any application requiring an inch-series unified coarse thread fastener with a pan head and slotted drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a correctly sized flat-blade screwdriver or bit to avoid cam-out and head damage. Ensure the mating tapped hole or nut is a 4-40 thread before driving to prevent cross-threading. Do not over-torque small-diameter machine screws, as the steel threads can strip in softer base materials such as aluminum or plastic. Consult applicable equipment service documentation for fastener torque requirements.\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: 0.25 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: Internal Tooth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.13a, 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\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: 0404ISP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693423788338,"sku":"0404ISP","price":1551.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6bb87ec0fef64f07643d183d7e85de.jpg?v=1788312168","url":"https:\/\/voomisupply.com\/products\/value-collection-0404isp-4-40-x-1-4-pan-head-slotted-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
