Built from steel with a zinc finish, it measures 0.125 inches in length under the head and conforms to ASME B18.6.3 and SAE J82 dimensional and material standards. The binding head profile seats flush against the work surface and resists loosening under vibration, making it well suited for light-duty fastening in electrical enclosures, panel assemblies, and instrument housings. This fastener is installed by electricians, panel builders, and mechanical assemblers working on precision assemblies where small-diameter threaded fasteners are required.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in residential and commercial applications where 4-40 threaded inserts or clearance holes are present. Typical install scenarios include securing terminal blocks, mounting small components inside electrical enclosures, and assembling instrument panels. The slotted drive accepts a standard flat-blade screwdriver, making it accessible with basic hand tools in tight quarters. Sold individually per package with a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 unified coarse thread for broad compatibility with standard 4-40 tapped holes and inserts\u003c\/li\u003e\n  \u003cli\u003eBinding head profile provides a low-profile, high-seating-force head without a separate washer\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers and is compatible with automated assembly tooling\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish provides corrosion resistance in dry indoor environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J82 for dimensional accuracy and material grade compliance\u003c\/li\u003e\n  \u003cli\u003eNo washer required — washer style is without washer per specification\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 any application requiring a binding head slotted fastener conforming to ASME B18.6.3 and SAE J82 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a flat-blade screwdriver sized to the slotted head to avoid cam-out and head damage. De-energize and lock out any electrical assembly before inserting or removing fasteners inside live enclosures in accordance with applicable NFPA 70 and OSHA lockout\/tagout requirements. Do not overtighten — small-diameter machine screws are susceptible to thread stripping in soft materials such as aluminum or plastic. Inspect threads on both the screw and the tapped hole before assembly.\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: Binding 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: 0.125 inches\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\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3 and 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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0007 pounds\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: 0402MSB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709145219378,"sku":"0402MSB","price":2309.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a8ffdf5115b7ad286127ea5dafc0dde.jpg?v=1788451942","url":"https:\/\/voomisupply.com\/products\/value-collection-0402msb-4-40-binding-head-slotted-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
