This fastener uses Unified National Coarse (UNC) thread form and is designed for general-purpose mechanical assembly where a low-profile rounded head and simple slotted drive are appropriate. The zinc coating provides baseline corrosion resistance in typical indoor or sheltered environments. Sold in minimum order quantities, this screw suits production assembly lines, maintenance shops, and field repair kits where standard inch-series fasteners are commonly specified.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light- to medium-duty mechanical assemblies in HVAC equipment, electrical enclosures, plumbing fixtures, and general industrial applications where 3\/8-16 UNC threading is called out. The round head profile sits flush against flat surfaces without requiring a countersink, making it a practical choice for panel attachment, bracket mounting, and equipment covers in both residential and light commercial trade work. A standard flat-blade screwdriver is all that is required for installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch length under head for shallow-grip applications\u003c\/li\u003e\n  \u003cli\u003eRound head profile requires no countersink preparation\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eGrade 2 alloy steel construction for general-purpose mechanical strength\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides basic corrosion resistance in typical service environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC machine screw for use in any tapped hole or with any nut specified for 3\/8-16 thread in general mechanical and trade applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires only a flat-blade screwdriver sized for a 3\/8-inch head slot. Always de-energize or shut down the equipment before fastening or removing hardware on electrical or mechanical assemblies. Do not overtighten alloy steel screws into softer base materials such as aluminum or plastic, as thread stripping can occur. Follow applicable equipment manufacturer torque guidelines where specified in service documentation.\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 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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy 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\u003eThread Form\u003c\/strong\u003e: UNC (Full Thread)\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: 583815PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51783584416050,"sku":"583815PR","price":3871.98,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8dc02d6b96b05418bab9d83097cfbc81.jpg?v=1789191451","url":"https:\/\/voomisupply.com\/products\/value-collection-583815pr-machine-screw-3-8-16-x-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
