Precision lock nuts with locking pins,KMT and KMTA lock nuts are intended for applications where high precision, simple assembly and reliable locking are required. The three, equally-spaced locking pins enable these lock nuts to be accurately positioned at right angles to the shaft. However, they can also be adjusted to compensate for slight angular deviations of adjacent components.

KMT and KMTA lock nuts should not be used on shafts with keyways in the thread or adapter sleeves. Damage to the locking pins can result if they align with either.

KMTA lock nuts are available for thread M 25×1,5 to M 200×3 (sizes 5 to 40)have a cylindrical outside surface and, for some sizes, a different thread pitch than KMT lock nuts are intended primarily for applications where space is limited and the cylindrical outside surface can be used as an element of a gap-type seal

KMT and KMTA series precision lock nuts have three locking pins equally spaced around their circumference that can be tightened with set screws to lock the nut onto the shaft. The end face of each pin is machined to match the shaft thread. The locking screws, when tightened to the recommended torque, provide sufficient friction between the ends of the pins and the unloaded thread flanks to prevent the nut from loosening under normal operating conditions .
