Constructed from AISI 1016 steel with a zinc plated finish for corrosion resistance, this screw has a length under head of 0.25 inches. It conforms to ASME B18.6.3 and ASME B18.6.4 dimensional standards, making it a reliable choice for applications that require consistent, specification-grade fasteners. Sheet metal mechanics, HVAC installers, and electricians will find this screw suited for everyday panel assembly and enclosure work.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in residential and commercial HVAC duct assembly, electrical panel and enclosure fabrication, and general sheet metal joining applications. The round head profile provides a broad bearing surface and is appropriate where a low-profile or pan head is not required. Sold individually but subject to a minimum order quantity of 1000 pieces per order, making this SKU appropriate for contractors and shops purchasing in bulk for ongoing production or service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI 1016 steel construction for consistent mechanical strength in light fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc plated finish provides basic corrosion protection in dry indoor environments\u003c\/li\u003e\n  \u003cli\u003eRound head profile delivers a broad bearing surface on sheet metal\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and ASME B18.6.4 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e0.25 inch length under head suits thin-gauge material fastening\u003c\/li\u003e\n  \u003cli\u003eGrade 1016-1024 material specification for consistent hardness and thread performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard No. 4 round head sheet metal screw for use in light-gauge steel sheet metal assemblies, HVAC ductwork, and electrical enclosures where ASME B18.6.3 and ASME B18.6.4 compliant fasteners are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSheet metal screws of this type are installed by licensed sheet metal mechanics, HVAC technicians, and electricians using a manual or powered screwdriver with the appropriate bit. Always ensure the material thickness is compatible with the screw length before driving to avoid stripping or pull-through. Follow applicable codes including SMACNA standards for duct assembly and NEC requirements for electrical enclosure fastening. Pre-drilling a pilot hole is recommended in harder or thicker gauges of steel to prevent material distortion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Round Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel (AISI 1016)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 1016-1024\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.6.3, ASME B18.6.4\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: 1000\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: R52000823\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701915451698,"sku":"R52000823","price":9632.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b7f0611b874fcca41e80100a4a98a06.jpg?v=1788406829","url":"https:\/\/voomisupply.com\/products\/value-collection-r52000823-size-4-sheet-metal-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
