The Surewinder and Brutewinder wrenches utilize torque stabilizing technology, ensuring a safer and more automated way to apply spring torque . The wrenches remove dangers inherent in winding bars such as lacerated hands, projectiles, ladder falls, and repetitive motion trauma which lowers worker compensation claims and lost work time.  Two days of lost work due to a simple muscle strain pays for the wrench.


Designed and tested by an aeronautical engineer.   Proven in the field for over 5 years.   Stainless steel gear housing and high temper bronze drive gear are designed for wear resistance.




The Surewinder and Brutewinder wrenches can wind and unwind springs up to 10 times faster than winding bars.  Increase your revenue by completing more jobs in a week!  These tools minimize fatigue, which will give you the energy to do more jobs in a day, safely!
