The screw measures 2.5 inches in overall length and is manufactured from Grade 2 steel with a zinc finish that provides basic corrosion resistance in light-duty indoor and sheltered environments. The flat head profile sits flush with or below the mating surface when countersunk correctly. The slotted drive accepts a standard flat-blade screwdriver. This screw follows the Unified National Coarse (UNC) thread standard at 3\/8-16, making it a widely interchangeable fastener for production, maintenance, and repair work across mechanical and structural trades.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is suited for residential and light commercial applications where a flush-mount fastener is required. Typical uses include equipment panel assembly, bracket mounting, and general mechanical repair where UNC-threaded holes or nuts are already present. The zinc finish makes it appropriate for dry or mildly humid indoor environments. It is not rated for outdoor marine or high-corrosion exposure. Installers in HVAC, plumbing, and electrical trades will recognize this as a standard hardware item for securing panels, junction boxes, brackets, and equipment enclosures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for broad compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n  \u003cli\u003eFlat head profile countersinks flush for a clean, low-profile installation\u003c\/li\u003e\n  \u003cli\u003eSlotted drive works with standard flat-blade screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for general fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc finish delivers basic corrosion resistance in dry and sheltered environments\u003c\/li\u003e\n  \u003cli\u003e2.5 inch overall length suits medium-depth fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC machine screw for use with any 3\/8-16 threaded hole, nut, or insert conforming to Unified National Coarse thread specifications in inch-measurement fastener applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fastener is installed by qualified tradespeople and assemblers using standard hand tools or power drivers fitted with a flat-blade bit. Ensure the mating hole is properly tapped or threaded to 3\/8-16 UNC before installation. For flush seating, use a correctly sized countersink to prepare the receiving surface. Do not overtighten, as Grade 2 steel has lower yield strength than higher-grade fasteners and is not intended for high-torque or high-tension structural joints.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 580871PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696313401650,"sku":"580871PR","price":4489.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64e88be34421d971755e59120d27b0f8.jpg?v=1788341363","url":"https:\/\/voomisupply.com\/products\/value-collection-580871pr-machine-screw-3-8-16-x-2-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
