Detail & Specs
5.5 Phillips Drive Truss Head TAPPING Screw / Black
Self-Tapping screws are meant to be installed directly into sheet metal. Tapping Screws require a pilot hole and tap their own threads during install. They cannot be used with machine thread tapped holes or machine thread nuts.
Zinc plated finish provides corrosion resistance
Head Style
These screws have an oversized "truss" head style with an undercut bottom, low height rounded dome top and recessed phillips drive.
The flat bearing surface underneath the head covers a larger diameter than a typical pan head screw. This increased surface area reduces the chances of crushing or marring the material the screw is tightened against.
A truss-style head is the preferred design in applications where minimal clearance exists above the head. Suitable for license plates.
Material
Made of steel, A black oxide finish provides minimal corrosion resistance, best for indoor, dry environments. This finish is not suitable for outdoor applications, and will rust when exposed to moisture.
