Screw spacing
This tool will help you check the minimum spacing and distances to be kept during screw installation. The calculations are based on PN-EN 1995-1-1 standard and the European Technical Approval ETA-13/0393.
Besides instantaneous information on what screws should be installed in what distance, the wizard answers the question of "How to choose the drill–driver torque for the screw driving torque?".
