Polyamide locking function

During the screwing process the layer of plastic put on the threads is compressed.

The radial tension created by the elastic deformation of the product increases the rubbing which triggers off the locking.

The locking is repositioned, as the deformation of the polyamide is partially reversible allowing the part to be tightened and untightened several times.The locking function is immediately active after tightening but the screwing torques are more sensitive than those that have been bonded.

To obtain the repositionable locking function,we place a cold polyamide resin, either just a drop or either on all the circumference of the threads. The breaking torque can therefore be adapted to the applications as required.

The polyamide deposit is particularly indicated for the adjustment screws meaning that this can be repositioned several times.

We also use this technique to “realize the provisional positioning” of pre-mounted screws, that are waiting to be tightened.

This type of repositionable locking is also known as “Nylon locking” and can also be used for parts that must be regularly dismounted.
