Description
The Fabco 688-0645 or 6880645 is a genuine OEM TN13 self-locking nut featuring Dri-Loc 201 pre-applied thread-locking compound. Dri-Loc is a dry, pre-applied adhesive/sealant that activates on installation, eliminating the need for separate liquid thread-locker and providing consistent locking torque. Fabco designates this as an off-highway product, making it applicable to Fabco transfer case, PTO, and steerable drive axle assemblies where a self-locking fastener with integral thread-locking compound is specified. Confirm fitment against your Fabco assembly service manual before ordering. Pro Gear and Transmission carries this as a genuine Fabco part.
