Torque Specifications

The tables below show the amount of torque in foot-lbs. and newton meters required to activate the 2 degree drop-lock feature for t-slotted profiles. Nut and bolt combination is preloaded when tightened to the minimum torque rating.

The estimated torque calculations in this chart are offered as a guide only. Use of this content by anyone is the sole responsibility of that person and they assume all risk. Due to many variables that affect the torque-tension relationship like human error, surface texture, and lubrication the only way to determine the correct torque is through experimentation under actual joint and assembly conditions.
