Unlike the rest of our standard shaft collars and couplings that have a single torque rating per screw size, plastic shaft collars are extremely dependent on collar size to determine acceptable torque limits. The following table should be used only as a guideline to tighten plastic collars. Due to the elastic nature of plastics, it is recommended that screw torque be applied in a slow and steady manner as to not induce extra shock into the plastic resulting in premature collar failure.
