S-Locknut

 MATERIAL:  stainless steel 303

Cross section of the S-Locknut 

HOW IT WORKS

  Mating with standard 60 deg. bolt threads, the asymmetric threads enables the nut to spin freely until locking occur.  Once nut is locked, its asymmetric threads eliminates radial clearance, creates a strong axial load and will not vibrate loose.  S-Locknut - self locking vibration resistant nuts  are reusable.
