Any ETA Tool Holder will mount on any ETA Torque Arm. This enables you to repurpose your arm to drive fasteners with different tools or in different attitudes (direction of drive). Please note that while any tool holder on this page will fit on any frame size, it might not always be practical due to weight limitations of the arm or the torque output of your tool. Consult with us, referring to your arm’s Serial Number, if you aren’t sure about repurposing your ETA arm for your new application. The Serial Number is located on the Forearm’s nameplate.
At the tool end of every standard ETA Forearm is a through hole with 1/4 NPT threads top and bottom and also a threaded 1/4-20 blind hole on the bottom edge, 1.0″ on center behind the NPT hole. All of our holders have a 1/8″ deep pocket that the Forearm sits into. A 3/8″ cap screw with a hardened flat washer drops down through the 1/4 NPT hole in the Forearm and threads into the holder body. A 1/4-20 cap screw comes up through the holder into the blind hole in the bottom of the Forearm. At any time the holder can be removed and replaced with a different holder.
