Value Collection -004U188 Round Head Sheet Metal Screw

Product Description

The VALUE COLLECTION -004U188 is a Type U round head sheet metal screw manufactured from Grade 18-8 stainless steel. 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.

This 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.

Key Features

• Type U spiral point drives into sheet metal without a pre-tapped thread
• Grade 18-8 stainless steel for corrosion resistance in wet or outdoor environments
• Round head profile for broad bearing surface on thin material
• 1/4 inch length under head suits thin-gauge sheet metal applications
• Conforms to ASME B18.6.3 and ASME B18.6.4 standards
• Sold in bulk quantity of 1000 units per order for production and service stock use

Compatibility

Designed 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.

Installation Notes

Sheet 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.
