Manufactured from steel with a zinc finish, this fastener measures 3\/8 inches in length under the head and conforms to ASME B18.6.3 and SAE J82 standards. The binding head profile sits low and wide, distributing clamping load across the bearing surface and resisting loosening from vibration. Suitable for electricians, HVAC technicians, panel builders, and general mechanical assemblers working with small-format threaded components.\u003c\/p\u003e\u003cp\u003eThis screw is used in applications requiring a small-diameter, fine-pitch fastener with a positive slotted drive. Common installations include electrical enclosures, control panels, instrument housings, small appliance assemblies, and light sheet-metal fabrication. The 4-40 thread is a standard size in North American fastener practice, making it widely compatible with tapped holes and threaded inserts machined or stamped to that specification. The zinc coating provides baseline corrosion resistance for indoor and sheltered environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 unified coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003eBinding head style provides wide bearing surface to resist pull-through and loosening\u003c\/li\u003e\n\u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers and bit drivers\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc finish for corrosion resistance in dry or sheltered indoor environments\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.6.3 and SAE J82 dimensional and material standards\u003c\/li\u003e\n\u003cli\u003eSold individually with a minimum order quantity of 100 pieces per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 x 3\/8-inch binding head machine screw for use in any application requiring a fastener conforming to ASME B18.6.3 dimensions and SAE J82 material grade.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a flat-blade screwdriver or slotted bit driver sized appropriately for the head recess to avoid cam-out and head damage. Ensure the mating tapped hole or threaded insert is clean and dimensionally correct for 4-40 threads before driving. De-energize and lock out any electrical panel or control enclosure before replacing fasteners in live equipment. Do not over-torque; binding head screws at this diameter are susceptible to thread stripping if driven beyond hand-tight plus a controlled final turn.\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\u003eLength Under Head\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Binding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\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: 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\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: 0406MSB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712140837170,"sku":"0406MSB","price":938.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c48827aa4dc534a407e1ea45c1e770f.jpg?v=1788484331","url":"https:\/\/voomisupply.com\/products\/value-collection-0406msb-4-40-x-3-8-in-binding-head-slotted-machine","provider":"Voomi Supply","version":"1.0","type":"link"}
