Value Collection 0808U Sheet Metal Screw Size 8 Round Head

Product Description

The VALUE COLLECTION 0808U is a Number 8 round head sheet metal screw designed for fastening thin metal panels, brackets, and light-gauge steel assemblies. It features a Type U drive point for self-starting in pre-drilled or punched holes. The shank is manufactured from Grade 1016-1024 steel with a zinc-plated finish that provides basic corrosion resistance in dry indoor applications. The length under head measures 0.5 inches. This fastener is sold in a minimum order quantity of 1,000 pieces and is sized for production, maintenance, and fabrication work performed by sheet metal workers, HVAC technicians, and general contractors.

This screw is suited for light-gauge sheet metal applications including HVAC ductwork, electrical enclosures, metal roofing panels, and general fabrication assemblies. The round head profile sits above the work surface and distributes clamping load over a wider area, making it appropriate for thin material that could deform under a flat or bugle head. It follows ASME B18.6.3 and ASME B18.6.4 dimensional standards, ensuring consistent fit across standard tooling and drivers.

Key Features

• Type U point for self-starting in pre-punched or pre-drilled sheet metal
• Round head profile distributes load and resists pull-through in thin gauge material
• Grade 1016-1024 steel construction meets AISI 1016 material standard
• Zinc-plated finish provides corrosion resistance for dry indoor environments
• Dimensionally compliant with ASME B18.6.3 and ASME B18.6.4 standards
• Length measured under head at 0.5 inches for consistent installation depth

Compatibility

Designed as a standard Number 8 round head sheet metal screw suitable for light-gauge steel sheet metal assemblies, HVAC ductwork panels, and general metal fabrication applications requiring ASME B18.6.3 or ASME B18.6.4 compliant fasteners.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, or electricians using a standard slotted or matching drive bit and a variable-speed driver or hand screwdriver. Pre-drill or punch the host material to the recommended pilot hole size for Number 8 sheet metal screws before driving. Do not overdrive — the round head should seat flush to the material surface without deforming the panel. Follow applicable installation and building codes for the specific assembly type.
