In previous articles, we have illustrated how to run a torque study to obtain important data about a fastener and joint. In particular, we saw how to determine the rundown phase, the seating point (where the head of the screw fully touches the material at the end of the rundown phase), the torque and angle values at the seating point, and the yield point at which the fastener fails.
Now, we are going to use this information to set the appropriate parameters in Kolver’s K-DUCER precision fastening system. But first, let’s briefly review joint types and how they affect our selection of the right parameters.
