Material
Lock nut: High strength steel
Finish: Phosphated and saturated with oil
Locking pin: Steel
Grub screw: Type MP6SS short pin, (DIN 913, 45H)

Thread tolerance 5H (ISO 965/3-1980)
Recommended tolerance for shaft threads: 6g (ISO 965/3-1980)

Features
Locks without a locking washer & keyway: The locking effect of the KMK lock nut is given by a loose steel insert, an integral part of the thread, being pressed against the shaft thread by a grub screw. Shaft keyways are not needed. Expensive machining is therefore avoided and shafts can be of a smaller diameter.

Effective locking: The steel insert is free to float both axially and radially. This ensures that it presses perpendicularly on the shaft. The friction within the nut thread is thus increased and effective locking obtained. The locking action of the steel insert has no effect on the runout of a mounted KMK lock nut.

Re-usable: The steel insert is pressed by a locking screw against the shaft thread without any deformation of the insert or thread. The locking effect is a function of frictional force alone. Since the locking insert is not deformed the KMK lock nut can be re-used with no loss of precision.

Axial force carried by the entire length of thread: Axial forces on the lock nut are carried by the nut thread flanks and not by the steel insert.

Simple to mount and dismount: KMK lock nuts are simple to mount and dismount. Four hook spanner notches are provided around the circumference.
The locking screw can be tightened using a standard hexagon key or a torque wrench.
A torque wrench is recommended to achieve an accurate loosening torque limit.

Close tolerances: The thread and locating face are machined in the same operation. The maximum runout between the thread and the locating face is 0.02mm.
