Precision Locknut

Once the nut is clamped, the material tends to break down. This leads to the loss of its elasticity, or the slits caused by mechanical vibrations result in both weak tension and friction. Thats how the loose stopper happens. Its important that the tension is always made to work on the thread for the screw to be tightened. The level describes 'Any slit' between an external thread and a nut, as well as the shape and dimensions. The combined thread with narrow slits in it can have a good level in the precision. A good example includes a combination of external thread 59 and nut 5H, external 4h and Nut 4H.
