Safe: Plastic Banding Roll can keep 5% tightening force with loosing in a long time. [...] WebbNormally the force required to untighten is checked, to know that the bolt is safe. Untightening torque is often not linear to the tightening torque; however, this is a somewhat more accurate and a reliable method compared to torque check inspections. It can seem a bit ironic to have to untighten (completely loosen) a bolt to know if it is safe.
