Secure Lock

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.
