Torque Reaction Arms and Ergonomic Tool Support Systems

Torque reaction arms and ergonomic tool support systems transfer the torque reaction of pneumatic and electric powered screwdrivers, nut runners, tappers, and drills away from the operator, reducing fatigue and improving safety. These assembly tool arms support the tool's weight, maintain proper alignment with fasteners to eliminate cross-threading and broken bits, and reduce drilling and tapping cycle times. Available in bench-mounted and overhead-mounted configurations with standard, medium, and heavy-duty capacities for tools up to 15 pounds.

What are the Benefits of Tool Assembly Systems?

As an ergonomic company, we focus on making life on the operator a little easier. A torque arm transfers the reaction of air and electric-powered screwdrivers, nut runners, tappers, and hand drills to the arm. Also, torque reaction arms support the weight of the tool, reducing the burden on the operator to constantly support a tool all day. They keep the drill driver tool in alignment with the fastener and workpiece. This eliminates cross threading, broken bits, screw head burrs, and out of square fasteners. It keeps expensive tools from being dropped or misplaced, and reduces drilling and tapping cycle times.

Ergonomic Tool Arms (ETA) are available in several styles. The most common models are tool arms for assembly, where there is repetitive drilling and tapping. The standard torque arm comes with the ability to float the tool and reduce torque. ETA also provides tool support systems that can be mounted overhead.
