KATO Linear Torque Arm

KATO Linear Torque Arm

Unprecedented smoothness of linear and rotational movements.

KATO Linear Torque Arm

KATO Linear Torque Arm (2KLRM-1) is a torque reaction arm, designed to install Tangless or tanged KATO CoilThread inserts using any KATO electric installation tool. Add the optional Air Tool Kit (2KLRM-1A), and the KATO Linear Torque Arm will work seemlessly with the KATO pneumatic installation tools.

The KATO Linear Arm offers an unprecedented smoothness of linear and rotational movements as it absorbs the torque reaction inherent with power installation tools. The KATO Linear Arm delivers ultra smooth vertical, horizontal, and rotational motion, provides ergonomic support for the operator, and reduces operator fatigue. The fluid movement of the KATO Linear Arm increases precision and production for a variety of applications.

KATO Linear Torque Arm

The Fastest & Most Productive Semi-Automatic Installation System!


Use the KATO Linear Arm with KATO strip-feed packaged Tangless inserts, and the KATO Prewinder Electric tool (2KPE series).

Features and Benefits

  • Keeps the installation tool perpendicular to the work piece.
  • Reduces RMI (Repetitive Motion Injury) and CTS (Carpal Tunnel Syndrome) while boosting production.
  • Prevents cross threading and side load, prolonging the life of installation mandrels.
  • Adjustable arm length.
  • Adjustable counter balance provides exceptionally smooth vertical movement.
  • Maneuvers smoothly as the arm absorbs torque reactions from electric and pneumatic tools.
  • Torque capacity of 177 in-lbf (20 Nm).
