Columbian
Columbian Prevailing-Torque Locknut
The unique design of the COLUMBIAN Locknut allows the optional positioning of the slotted locking element to be placed on the side of this locknut in order to create frictional thread interference where it is most needed. COLUMBIAN Prevailing-Torque Locknuts are available in American Standard and Metric, hex-finished, jam, heavy, hi, square, acorn, weld, track, and flange nuts. For special applications, COLUMBIAN locknuts are available in special light or heavy torque versions.
