Ribbed lock washers

Ribbed lock washers

Small washers with great effect

Our newly developed ribbed lock washer combines simplicity with technical sophistication. Its one-piece locking system secures your bolted connection against self-loosening.

Junker test according to DIN 65151 and DIN 25201-4

The locking effect of all dimensions was confirmed by an independent institute via a Junker test according to DIN 65151 and DIN 25201-4.

The residual preload of the bolted connection was still at least 80% after the test.

How do ribbed lock washers work?

Due to the preload applied during assembly, the radial ribs of the W.TEC®SMARTLOCK ribbed lock washer press into the mating material.

This process results in a form-fit connection of the respective contact surfaces. This form fit in combination with the angles α and β ensures reliable locking against loosening even under strong dynamic influences and vibrations.
