Never a screw loose again

Wedge lock washers

Avoid a loose screw connection becoming a risk

HEICO-LOCK® Keilsicherungsscheiben

Dear ,

Whether in the navy, in plant construction, in architecture or in the hobby sector - safety-relevant screw connections must deliver what they promise!

Frequently, shocks and vibrations put them to the test. As a result, the bolted connections may gradually loosen automatically. If the design conditions only allow a short clamping length of the bolts, this additionally increases the risk of the bolted connections loosening due to the constant dynamic loads. With increasing loss of pretensioning force, the probability increases that the bolted connection will loosen completely.

The HEICO-LOCK® wedge lock washers counteract this: Unlike other screw locking elements which are based on friction, the wedge locking principle is based on maintaining the pretensioning force.

HEICO-LOCK® Keilsicherungsscheiben

The wedge lock washers consist of two individual washers that are connected to each other in pairs. On the respective outer sides of the pair of washers there are radial ribs which impress themselves positively into the component surface and into the head rests of the bolt or nut when the bolt connection is pretensioned.
On the inside of the pair of wedge lock washers there are wedge surfaces facing each other, which effectively prevent the screw from loosening automatically due to their wedge surface angle, which is always greater than the pitch angle of the screw thread. After tightening the screw connection, system movements are only possible between the internal wedge surfaces. The pre-tensioning force is maintained and thus permanently prevents the screw from loosening automatically due to vibrations and dynamic loads.
