Note: Extrusion conforming to DIN 17 615 specifications. Unless otherwise specified, all profiles will have etch and clear (MIL-A-8625F) anodizing with depth of .0004 inches (0.010mm) and surface hardness of approximately 250 HV (anodized profiles should not be welded because of toxic fumes).

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.
