New nipple locking system (patented)
The patented Secure Lock nipple of Sapim is a locking mechanism that prevents nipples from untightening.
The advantages of this easy locking system are:
- Can be used on truing machine
- No loose function while truing the wheel
- Available on most current Sapim nipples
- Easy to recognize
Highly precise and accurate punching machines are needed to form this type of locking system in order to achieve a stable and well defi ned deformation on the thread. Each nipple has an additional locking resistance of 18 +/- 3 cNm.
