← Back Jenbacher 196403 Disc tab washers

The Jenbacher 196403 is a Disc Tab Washer, a specialized locking washer used to secure critical nuts and bolts within Jenbacher gas engines. After a fastener is tightened, the washer's tab is bent up against a flat on the fastener's head, physically preventing it from loosening due to vibration. This is essential for maintaining the integrity of key bolted joints, such as those on main bearings or connecting rods.
