ESSVE Overlap screw with release designed for installation of sheet-metal on beams, sheet-metal on light beams, and sheet-against-sheet (overlap) indoors.

The screw is produced in hardened carbon steel with bright zinc plated surface treatment. It is equipped with hex head.
The screw is self drilling and tapping. Release means the part of the screw below the head which has no thread so that it can rotate in the attached plate so that the plates are drawn together.

A screwdriver with a depth stop should be used for quick and efficient installation. Recommended rpm: 1800-2500/min
