The EJOT SHEETtracs® is a self-tapping screw for reliable thin-sheet-metal joints with a pilot hole. The online tool SHEETtracs® Basic Calculator enables the user to determine the relevant values for the fastening application by entering the materials and sheet thicknesses that are to be joined. These values include, among others, the required pre-hole diameter and a recommended tightening torque for different screw surfaces.
