Torque Control Wrenches With the Reaction Arm Built Into the Socket

GWY’s TONE-brand torque control wrenches are non-impact, versatile, and quiet. Because of that, these wrenches will change the way you work construction of bridges, buildings, and industrial applications. For example, they can be used for snug tightening of bolts or as a calibrated wrench. Also, these wrenches can be used in conjunction with your DTI fasteners. Furthermore, the fastening process is greatly simplified with these torque control wrenches because you can preset them to your torque requirement. In addition, they even shut off when the torque requirement is reached.
