It uses a Unified National Coarse (UNC) thread form and is measured by overall length. The flat head profile sits flush with or below the surface of the mating material, making it well suited for applications where a low-profile fastener is required. Grade 18-8 stainless steel provides solid corrosion resistance in general-purpose indoor and outdoor environments. These screws are sold in a minimum order quantity of 100 pieces per package and are appropriate for light mechanical assembly work performed by technicians, equipment fabricators, and maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light-duty mechanical assemblies, electrical enclosures, control panels, and instrumentation brackets where a small-diameter threaded fastener is needed. The 4-40 thread size is common in electronics, HVAC controls, and similar applications that call for fine, precise fastening in thin or tapped metal and plastic components. The slotted drive is compatible with standard flat-blade screwdrivers. No washer is included or required by design, as the fastener is intended for direct flush-seat installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread for precise engagement in tapped holes in metal and plastic\u003c\/li\u003e\n  \u003cli\u003eFlat head profile allows flush or countersunk seating\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with no washer, suitable for clean-assembly environments\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 100 for job-site and shop restocking efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose UNC machine screw for use in any application that accepts a 4-40 tapped hole, including control enclosures, panel boards, electronics assemblies, and light mechanical components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard flat-blade screwdriver sized to the slotted head. Ensure the receiving hole is properly tapped to 4-40 UNC specifications before driving the screw to avoid cross-threading. Do not overtighten stainless steel fasteners in stainless or aluminum tapped holes, as galling can occur. Follow applicable mechanical and electrical enclosure codes when fastening within listed 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat\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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 package (minimum order 100 pieces)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\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: R63062960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692553404722,"sku":"R63062960","price":737.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/584586ed3a45f473140fbfd6207c8463.jpg?v=1788299174","url":"https:\/\/voomisupply.com\/products\/value-collection-r63062960-flat-head-machine-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
