  • Unnecessary to add any tooth lock washer.
  • Unnecessary to mill a keyway on the shaft and shorten its assembled time.
  • Allow to be used after repeatedly screwing.
  • Bearing any vibration and ensuring the integrated resistance when not tightened.
  • The surface is galvanized to prevent rust.
  • Standards: M10-M100.
  • Material: SS41
  • Nylon material: PA6

Basic principles :
Prevailing torque bearing nut adds the special tightly-locking ring of spring steel according to the engineering principles. When used, the ring of spring steel clip and presses into the solt. It's effects of shockproof and prevention of loosening are 100%, and it would not affect the thread of the screw and the tightly-locking ring of spring steel after friction again and again. In the variation of temperature from -30¢Xc to +300¢Xc and erosion of all kinds of oli(such as gasoline. petroleum. alcohol. etc), its tightly-locking ability is not affected at all.
