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.

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.
