Compliance and Restrictions



Get precise tightening or loosening of heavy-duty bolted connections with smooth and steady use of a torque multiplier. Tightening bolts using a multiplier removes a lot of the physical effort and helps you apply torque more accurately. Use instead of a long lever in tight spaces.
