Manufactured from steel with a zinc finish, this screw features a round head profile and slotted drive, making it compatible with standard flat-blade screwdrivers. The 1-inch length is measured under the head per ASME B18.6.3 and SAE J82 standards. Grade J82 construction ensures consistent dimensional tolerances and mechanical properties suitable for general industrial, electrical, and instrumentation applications where a small-diameter threaded fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in control panels, electrical enclosures, instrument housings, light-duty brackets, and similar assemblies where a 4-40 threaded hole or nut is present. The zinc finish provides basic corrosion resistance in dry indoor environments. Electricians, HVAC technicians, and mechanical assemblers commonly use 4-40 slotted round-head screws when securing terminal strips, small covers, and lightweight components to sheet metal or threaded standoffs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 unified coarse thread for reliable engagement in standard 4-40 tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eRound head profile with slotted drive for use with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003e1-inch length under head per ASME B18.6.3 and SAE J82 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for basic indoor corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eGrade J82 material designation ensures consistent dimensional and mechanical tolerances\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 100 units minimum order quantity\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 round-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 fit the slotted head to avoid cam-out and head damage. Ensure the mating thread is clean and properly tapped to 4-40 UNC before installation. Do not overtighten small-diameter screws, as stripping is common when excessive torque is applied. Power down any electrical enclosure or panel before inserting or removing fasteners inside live equipment.\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: Round\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 inch\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 0416MSR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722315497778,"sku":"0416MSR","price":530.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e571aa1b2ddf7f0d0492ebb65fce5bc.jpg?v=1788589201","url":"https:\/\/voomisupply.com\/products\/value-collection-0416msr-4-40-x-1-in-round-head-slotted-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
