WebbThe thin nut should be placed on the bolt first. This nut is typically tightened to between 25% to 50% of the overall tightening torque. The second (thick) nut is then placed on the bolt and the thin nut held to prevent rotation by a spanner whilst the thick nut is tightened to the full torque value. WebbThe basic screw clamp uses the torque developed by a screw thread to hold a part in place. This is done by direct pressure or by acting on another clamp. (Refer Fig. 28.37). There are variations of the screw-type clamp. Numerous styles of commercial clamps have been developed to include advantages of the screw clamp and reduce its disadvantages.
