Value Collection -003U Round Head Sheet Metal Screw

Product Description

The VALUE COLLECTION -003U is a round head sheet metal screw designed for fastening sheet metal and light-gauge materials in mechanical, HVAC, electrical, and general trade applications. This screw features a Type U point for self-starting penetration without a pre-drilled pilot hole in many sheet metal gauges. Constructed from Grade 1016-1024 steel with a zinc-plated finish, it provides corrosion resistance suitable for typical indoor and light-duty installations. The 3/16-inch length is measured under the head per standard length measurement conventions.

This fastener is commonly used in HVAC ductwork assembly, electrical enclosures, sheet metal fabrication, and light mechanical assembly tasks. The round head profile seats flush against the material surface without countersinking, making it appropriate for applications where a low-profile but non-flush head is acceptable. Sold in multiples of 1,000 units, it is suited for contractors and shops with ongoing volume fastening needs across sheet metal work.

Key Features

• Type U point for self-starting entry into sheet metal without pre-drilling in many gauges
• Round head profile provides a clean, low-profile seating surface
• Grade 1016-1024 steel construction for reliable mechanical strength
• Zinc-plated finish for corrosion resistance in standard indoor environments
• Meets AISI 1016, ASME B18.6.3, and ASME B18.6.4 standards
• Length under head measured at 3/16 inches per inch system of measurement

Compatibility

Designed as an OEM-style replacement and general-use fastener for sheet metal assemblies requiring a round head, Type U point screw in 3/16-inch under-head length.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, electricians, and general tradespeople using a manual or powered screwdriver with the appropriate round head drive bit. Ensure the workpiece is secure and free of burrs before driving. Follow applicable code requirements including SMACNA standards for ductwork fastening when used in HVAC assemblies. Do not overdrive, as overtorquing sheet metal screws can strip the sheet metal or damage the screw head.
