Secure Lock

New nipple locking system (patented)

The patented Secure Lock nipple of Sapim is a locking mechanism that prevents nipples from untightening.

  • Can be used on truing machine
  • No loose function while truing the wheel

Highly precise and accurate punching machines are needed for this type of locking system in order to achieve a stable and well defined deformation on the thread. Standard locking resistance of 12 cNm.
