Value Collection 0806U188 Sheet Metal Screw 8 Round Head

Product Description

The VALUE COLLECTION 0806U188 is a size 8 round head sheet metal screw designed for fastening into pre-formed holes in sheet metal, light-gauge steel, and similar materials. It features a Type U point, which is a blunt, interference-fit point that is pressed or driven into a punched or drilled hole for a secure hold. The screw measures 3/8 inches in length under the head and is manufactured from Grade 18-8 stainless steel, providing corrosion resistance in humid or chemically active environments. This fastener meets ASME B18.6.3 and ASME B18.6.4 dimensional standards. It is commonly installed by HVAC technicians, sheet metal fabricators, and plumbers working with ductwork, enclosures, and light structural assemblies.

This screw is suited for light-gauge sheet metal applications including HVAC ductwork, electrical enclosures, junction boxes, and fabricated metal components. The round head profile distributes clamping load across a wider bearing surface, making it appropriate where a low-profile flat head is not required. The 18-8 stainless steel construction makes it a practical choice in installations exposed to moisture, condensation, or mild corrosive conditions such as those found in mechanical rooms, rooftop equipment, and outdoor enclosures.

Key Features

• Size 8 thread with 3/8 inch length under head for light-gauge fastening applications
• Type U blunt point designed for use in pre-punched or pre-drilled holes
• Round head profile provides broad bearing surface and clean finished appearance
• Grade 18-8 stainless steel construction resists corrosion and oxidation
• Conforms to ASME B18.6.3 and ASME B18.6.4 dimensional standards

Compatibility

Designed as a standard inch-series sheet metal fastener suitable for use in light-gauge sheet metal, HVAC ductwork, electrical enclosures, and similar fabricated metal assemblies requiring a size 8 round head Type U screw.

Installation Notes

Sheet metal screws of this type are typically installed by HVAC technicians, sheet metal workers, or electricians using a hand screwdriver or power driver with the appropriate bit. Ensure the receiving hole is correctly sized for a Type U interference fit before driving. De-energize any electrical equipment and shut off HVAC systems before fastening components to live assemblies. Follow applicable codes including SMACNA duct construction standards and NEC requirements for electrical enclosure work.
