Value Collection -004U Round Head Sheet Metal Screw No. 0

Product Description

The VALUE COLLECTION -004U is a round head sheet metal screw designed for fastening thin metal assemblies and light sheet metal work. It features a Type U drive point for self-starting penetration without a pilot hole in many applications. Manufactured from grade 1016/1024 steel with a zinc finish for basic corrosion resistance, this screw measures 1/4 inch in length under head and carries a No. 0 thread size. It conforms to AISI 1016, ASME B18.6.3, and ASME B18.6.4 standards. HVAC fabricators, electricians, and sheet metal workers commonly stock this fastener for duct work, panel assembly, and electrical enclosure installation.

This screw is suited for light-gauge sheet metal applications in residential and commercial settings. The small No. 0 thread size and short 1/4-inch shank make it appropriate for thin material stacks where a larger fastener would strip or deform the workpiece. Typical uses include securing HVAC duct panels, attaching light electrical enclosure covers, and general sheet metal fabrication tasks requiring a compact, low-profile round head fastener.

Key Features

• Round head profile provides a low-profile, finished appearance on exposed sheet metal surfaces
• Type U point allows self-starting entry into thin gauge metal without pre-drilling in many applications
• Grade 1016/1024 steel construction for reliable strength in light-duty sheet metal fastening
• Zinc finish provides basic corrosion resistance for indoor and protected environments
• Meets AISI 1016, ASME B18.6.3, and ASME B18.6.4 standards for dimensional and material consistency
• No. 0 thread size and 1/4-inch length under head suited for thin material stacks

Compatibility

Designed as an OEM-style replacement and general-use fastener for light-gauge sheet metal assemblies requiring a No. 0 round head Type U sheet metal screw with 1/4-inch length under head.

Installation Notes

Sheet metal screws of this type are typically installed by HVAC technicians, sheet metal fabricators, and electricians using a manual or powered screwdriver with the appropriate bit. Power down or de-energize any electrical enclosure or HVAC system before fastening covers or panels. Avoid over-torquing, as the small thread diameter can strip thin gauge material easily. Follow applicable SMACNA duct construction standards or NEC enclosure requirements as dictated by the installation.
