WebThe required tightening torque can be determined theoretically with the following equation: The screwing and the thread-stripping torques are to be determined in experiments. A secure directly screwed plastic joint can only be made with torque-controlled and rotation-angle controlled assembly equipment. The screwing speed is to be selected WebOnce you’ve drilled the hole, insert the most suitable size of screw extractor into the hole you’ve just made, tap it in with a hammer to ensure a secure fit, and then proceed as normal to attempt to turn the extractor counterclockwise using the added torque from a tap-and-die kit handle or similar Different types of grub screw
