Value Collection 0705U Sheet Metal Screw Size 7 Round Head

Product Description

The VALUE COLLECTION 0705U is a Type U round head sheet metal screw designed for fast, reliable fastening in light sheet metal and thin-gauge fabrication work. Manufactured from Grade 1016/1024 steel with a zinc finish for corrosion resistance, this screw features a Type U point that drives without a pre-drilled pilot hole in many applications. The thread size is #7, and the length under head measures 5/16 inches. It conforms to ASME B18.6.3 and ASME B18.6.4 standards, making it a code-compliant choice for HVAC sheet metal, electrical enclosures, and general trade assembly.

This screw is suited for residential and commercial applications where thin sheet metal panels, ductwork flanges, junction box covers, or similar substrates need a secure, flush-profile round head fastener. Electricians, HVAC technicians, and sheet metal workers commonly use this style of fastener for panel assembly, cover attachment, and light structural joining of metal components. The zinc coating provides baseline protection in dry indoor environments.

Key Features

• Type U point for self-driving installation in thin sheet metal without a pilot hole in many gauges
• Round head profile distributes clamping load and sits proud of the work surface
• Grade 1016/1024 steel construction for consistent tensile and shear strength
• Zinc finish for corrosion resistance in standard indoor service environments
• Meets AISI 1016, ASME B18.6.3, and ASME B18.6.4 dimensional and material standards
• Inch measurement system, #7 thread size for broad tooling compatibility

Compatibility

Designed as a standard #7 round head Type U sheet metal screw for use in light-gauge sheet metal assemblies, HVAC ductwork, electrical enclosures, and similar thin-metal fastening applications where ASME B18.6.3 and B18.6.4 compliant fasteners are specified.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or electricians using a standard Phillips or slotted bit driver matched to the screw head recess. Verify that substrate gauge and material are compatible with the Type U point before driving without a pilot hole, as harder or thicker stock may require pre-drilling. Follow applicable codes such as the SMACNA duct construction standards or NEC requirements for enclosure fastening when used in electrical applications. Use proper torque control to avoid stripping the head or deforming thin sheet metal.
