Itw Buildex 560110AP No. 9 Hex Washer Sheet Metal Screw 100pk

Product Description

The ITW BUILDEX 560110AP is a No. 9 steel sheet metal screw designed for fastening sheet metal and light-gauge steel assemblies in HVAC ductwork, electrical enclosures, and related metal fabrication applications. The hex washer head provides a wide bearing surface and a built-in washer-style flange, while the hex drive delivers high torque transfer with minimal cam-out. At 3 inches measured under the head, this screw handles thicker stacked assemblies or installations requiring extra thread engagement. Each package contains 100 screws.

This screw is suited for residential and commercial applications where technicians need a reliable fastener for joining sheet metal panels, securing duct sections, or attaching metal components to light-gauge steel framing. The hex drive style is compatible with standard 1/4-inch hex bit drivers and nut drivers, making it a common choice for HVAC installers, sheet metal workers, and electricians working with metal enclosures and junction boxes.

Installation Notes

Sheet metal screws of this type are installed by licensed sheet metal workers, HVAC technicians, and electricians. De-energize any electrical enclosures and shut down HVAC systems before fastening or removing panels. Use a 1/4-inch hex nut driver or a drill with a hex bit at controlled speed to avoid stripping the sheet metal. Follow applicable codes such as SMACNA duct construction standards and the NEC for enclosure fastening requirements.
