New conical clutch washer springs offer more constant clutch operation for maximum punch. Set of 0.4mm washers (8pcs) and 0.6mm washers (8pcs).
When utilizing the standard spring, after the clutch is placed for the first time the spring becomes deformed in the long run and needs retightening. This brand new conical clutch washer spring set permits the clutch to retain its setting for a long time without needing readjustment.
