It is very important to perform the initial adjustment of the screwdriver before use to ensure that the fastening is done efficiently. Avoid leaving too much space between the screw and the base, or applying excessive torque, which can cause the EPDM washer to be crushed. These situations compromise the screw’s sealing performance.
