Low noise and low vibration allow for efficient primary tightening operations.
◎Torque adjustment according to bolt size The KR-2024-1 and KR-2024-2 allow for the setting of tightening torque according to the size of the tightening bolt. Additionally, the GKR series features a torque adjustment knob that enables the adjustment of the strength of the tightening torque. The torque adjustment knob is equipped with a locking mechanism to prevent unexpected setting shifts during work. *Note: Adjustments are for reference only. ◎Bolt axis rotation prevention mechanism A mechanism that fixes the bolt axis during tightening and prioritizes the rotation of the nut is adopted to prevent bolt axis rotation. *If axis rotation occurs, it can lead to inadequate tightening, such as not achieving accurate axial force. ◎Corner type for narrow spaces A corner type designed with a short overall length of the wrench is also available to accommodate work in narrow areas. It is suitable for tightening in narrow spaces where standard models cannot be used, such as U-rib sections of bridges, truss sections, repair work, and seismic reinforcement work.
