Self-locking nuts
The Self Lock Nuts
A security principle made of 100% stainless steel, without any use of nylon or plastic.
Nuts with their internal thread form the counterpart of a screw and ensure that the attached screw does not come loose. Under heavy loads of the screw connections, it may sometimes loosen on its own which ultimately leads to a failure of the connection. This is easily caused by external influences such as weather or corrosion. However, proper bolt locking should hold a bolted connection even under dynamic loading and heavy vibration or impact.
The special shape of the thread of the Self Lock Nuts effectively prevents failure and at the same time reuses the nut. The number of components is also reduced by the self-locking feature of the nut, since no further securing elements are needed. The screw lock counteracts the unintentional release, without the need to process the screw itself.
Function of the thread lock
The Self Lock Nuts are made with a specific tap that cuts a self-locking thread on the nut. Thus, the thread lock is already "installed" in the internal thread. This modified thread profile consists of wedge surfaces which point in the loading direction. These wedge surfaces have a pitch angle of 30 ° and thus lead to a self-locking.
Securing
The pictures show the thread geometry. Here, the wedge surfaces are clearly visible on the right side of the thread. This angle, which acts selectively on the thread of the screw, creates the inhibiting effect and thus the securing of the Self Lock Nut.
