Measuring 7\/8 inches in length under the head, this fastener conforms to ASME B18.6.3 and SAE J82 standards, making it a reliable choice for precision assembly work where consistent thread engagement and head geometry are required. The fillister head offers a taller profile and smaller diameter than a pan head, giving it added grip depth for slotted drivers in confined clearances. Trade professionals and maintenance technicians rely on this screw type for light-duty mechanical assemblies, electrical enclosure hardware, and instrumentation panel work.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for applications requiring a fine 4-40 thread pitch in steel construction, including control panel assembly, electrical equipment mounting, and light-gauge sheet metal or plastic fastening. The zinc finish provides a basic level of corrosion resistance appropriate for indoor and sheltered environments. Sold in a minimum order quantity of 100 pieces per order, this screw is stocked for use in production, repair, and MRO settings where small-diameter machine screws are consumed in volume.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread size for standard fine-pitch mechanical assembly\u003c\/li\u003e\n  \u003cli\u003eFillister head profile provides deep slotted drive recess for positive driver engagement\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch length measured under the head per ASME B18.6.3 convention\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for basic corrosion protection in indoor environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eNo washer — clean bearing surface for direct substrate contact\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC machine screw suitable for use in any application calling for a 4-40 fillister head slotted fastener per ASME B18.6.3 and SAE J82 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard flat-blade screwdriver sized to the slotted recess to avoid cam-out and head damage. Ensure the mating tapped hole or threaded insert is clean and properly sized for 4-40 UNC threads before driving. Do not overtorque — small-diameter machine screws are susceptible to thread stripping and head shear. For electrical or control panel assemblies, follow applicable NEC guidelines for hardware used in enclosure construction.\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: Fillister\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: 7\/8 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: SAE 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, 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 (Minimum Order: 100 pieces)\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: 0414MSL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706192068914,"sku":"0414MSL","price":1983.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3a3517835be6fc7c0d25d9b51422792.jpg?v=1788433190","url":"https:\/\/voomisupply.com\/products\/value-collection-0414msl-4-40-x-7-8-in-fillister-slotted-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
