PRODUCT TYPE:
TREP® and TREP INOX® SPRING WASHERS

Description of TREP® washers

The TREP® spring washer is made up of three or four smooth, inseparably assembled tapered spring washers.

Whether they are made in heat-treated carbon steel or stainless steel, TREP® and TREP INOX® guarantee the same function and the same performance levels in a small footprint.

They are available for all bolt sizes and support all finishes, depending on the anti-corrosion requirements.

TREP® functions

Assembly diagram for a Trep® spring washer The TREP® spring washer maintains a high level of tension in the screw while conserving considerable elastic energy stored in a small volume.

This washer guarantees that the assembly will not loosen in the event of crushing, material expansion, wear or vibration. It compensates for expansion gaps and its elasticity maintains optimal tension in the screws and bolted assembly.

 

See the illustration below: at 0.1mm crushing, the assembly is loosened, but with a TREP® spring washer, it loses none of its tension.
