DISC Hexagon Washer

For bolting without rotation and with optimized fiction

DISC hexagon washers make preloading of bolted joints with hex nuts much easier. The calibrated torque of the assembly tool is transformed into a reproducible preload force through the constant friction coefficients. The DISC ensures that the joined elements and the locknut do not turn during assembly. Traditional backup wrenches are no longer needed and the assembly tools can be fitted directly on the DISC.
