KM12 Extension Tube
Sockets designed for easy tightening and loosening of lock nuts in a safe manner. They are used to secure and adjust bearings on tapered journals, adapter sleeves and withdrawal sleeves. Easy mounting and dismounting without nut damage. The socket demands less space around the bearing arrangement than when using a hook spanner and allows the use of ratchets and torque wrenches via a 1/2" drive.
