These torque control wrenches are versatile and quiet non-impact wrenches that will change the way you do construction of bridges, buildings, and industrial applications. They can be used for snug tightening your bolts or they can be used as a calibrated wrench. You can even use them in conjunction with your  DTI fasteners. Your fastening process is greatly simplified because with these torque control wrenches you can preset them to your torque requirement and they just shut off when the requirement is reached.
