Features
A high precision lock nut: The thread and clamping face are machined in the same set-up. The maximum runout between locating face and thread is 0.005mm.

Locks without a locking washer and keyway: KMT lock nuts are locked by 3 radial brass pins which are arranged at the same angle as the thread flanks. The locking faces of the pins and the nut thread are machined in a single operation. Shaft keyways are not needed. Thus expensive machining is avoided and shafts can be of a smaller diameter.

Simple to align perpendicular to the shaft: KMT lock nuts can be very accurately aligned at right angles to the shaft. The three locking screws enable the nuts to compensate for inaccuracies in adjacent components. The use of a KMT lock nut will therefore minimise radial and axial runout in most assemblies.

Withstands high axial loads: The KMT design features a very long thread which accommodates high axial forces.

Ensures very effective locking: The locking screws have a relatively large diameter so the thread locking force is high with even a moderate tightening. The locking forces are applied in the best possible way because the brass locking pins do not experience any axial forces.

Re-usable: The brass locking pins do not deform when pressed against the shaft thread by the locking screws. The locking effect is provided entirely by frictional forces. KMT lock nuts can be used time and time again without any loss of precision because the locking elements are not deformed in service.

Simple to mount and dismount: KMT lock nuts are simple to fit and dismount. All nuts incorporate hook spanner notches and additionally up to size 15 (M75 x 2) two spanner flats. The choice of spanner type depends upon the application. The locking grub screws can be tightened using a standard hexagon key or torque wrench. A torque wrench is recommended if an accurate loosening torque limit is required.
