Value Collection 0004U Round Head Sheet Metal Screw

Product Description

The VALUE COLLECTION 0004U is a round head sheet metal screw designed for fastening applications in light sheet metal, plastics, and composite materials. It features a Type U point for self-starting penetration without pre-drilling in many applications. Manufactured from Grade 1016-1024 steel with a zinc-plated finish, this screw offers corrosion resistance suitable for general-purpose interior and light-duty applications. The 0.25-inch length is measured under the head per standard length measurement convention. This fastener is installed by electricians, HVAC technicians, plumbers, and sheet metal workers as part of routine equipment assembly and enclosure fabrication.

This screw is used across residential and light commercial applications wherever thin-gauge sheet metal panels, junction boxes, equipment enclosures, ductwork components, or similar assemblies require a reliable threaded fastener. The compact 0.25-inch under-head length makes it well suited for shallow-material applications where fastener protrusion must be minimized. Trades commonly stock this screw for HVAC cabinet assembly, electrical enclosure work, and general sheet metal fabrication tasks.

Key Features

• Round head profile provides a wide bearing surface and flush-friendly appearance on sheet metal panels
• Type U point design allows self-starting entry into pre-punched or thin sheet metal without a separate pilot step in many cases
• Grade 1016-1024 steel construction delivers consistent shank strength for typical sheet metal fastening loads
• Zinc-plated finish provides basic corrosion resistance for interior and sheltered installations
• 0.25-inch length under head suits shallow-gauge material applications where minimal thread engagement is required
• Meets AISI 1016, ASME B18.6.3, and ASME B18.6.4 standards for dimensional and material consistency

Compatibility

Designed as a general-purpose sheet metal screw suitable for light-gauge steel panels, electrical enclosures, HVAC equipment cabinets, and similar thin-material fastening applications where a round head, Type U point, and 0.25-inch under-head length are specified.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, electricians, or plumbers depending on the application. Use an appropriate driver bit matched to the round head drive recess to avoid cam-out and fastener damage. Always de-energize electrical enclosures and shut down equipment before fastening or removing hardware on live assemblies. Do not over-torque, as the short shank length leaves limited thread engagement in thin-gauge material.
