The Tensor STR is the new standard in nutrunners, both for functionality and ergonomics. The various STR models feel good in the operator’s hands, with an excellent hand grip and have an optimum power-to-weight ratio. The STR runs 20% cooler than previous models and the new Tensor motor is 10% faster. The improved trigger gives more of a click feeling when pressed. Clear operator feedback is available from standard multi-color LEDs and from available attachments that can show operator instructions and torque and angle readings. All of these advances make for a more comfortable operator that is more in tune with what is occurring with each rundown.
