With a length under head of 1\/4 inch, this fastener is designed for light-duty sheet metal joining and attachment applications. The Type U point style is a spiral-point design that drives into pre-formed or self-formed holes in thin metal material without requiring a nut. Grade 18-8 stainless steel construction provides corrosion resistance suitable for interior and exterior environments where moisture exposure is a concern. This screw is sold in a minimum order quantity of 1000 units, making it appropriate for production, assembly, or bulk service stock.\u003c\/p\u003e\u003cp\u003eThis fastener is used in light commercial and residential applications where thin-gauge sheet metal panels, brackets, or housings must be secured. Common installation scenarios include HVAC duct fabrication and panel attachment, electrical enclosure assembly, and general sheet metal fabrication work. The round head profile sits above the material surface and distributes clamping load over a wider area, which is preferred when working with softer or thinner gauge stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType U spiral point drives into sheet metal without a pre-tapped thread\u003c\/li\u003e\n\u003cli\u003eGrade 18-8 stainless steel for corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n\u003cli\u003eRound head profile for broad bearing surface on thin material\u003c\/li\u003e\n\u003cli\u003e1\/4 inch length under head suits thin-gauge sheet metal applications\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.6.3 and ASME B18.6.4 standards\u003c\/li\u003e\n\u003cli\u003eSold in bulk quantity of 1000 units per order for production and service stock use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Type U round head sheet metal screw for use in thin-gauge metal assemblies where a spiral-point fastener is specified per ASME B18.6.3 and ASME B18.6.4.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSheet metal screws of this type are installed by sheet metal workers, HVAC technicians, and electricians using a standard slotted or appropriate bit driver. Ensure the workpiece is de-energized and secured before fastening electrical enclosures or HVAC panels. Do not overtighten, as the thin material can strip or deform around the screw head. Consult applicable SMACNA or NEC guidelines for fastener spacing and material requirements in your specific application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/4 inch\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: Grade 18-8\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1000 units minimum order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: -004U188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691977376050,"sku":"-004U188","price":8646.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/771076deb1d4e3836ef44d25f36e867c.jpg?v=1788291653","url":"https:\/\/voomisupply.com\/products\/value-collection-004u188-round-head-sheet-metal-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
