The Evans Torque Key has an ergonomic grip for maximum comfort, a knurled knob for quick spinning, and a slip-resistant magnetized head that holds the key in place for fast tightening and loosening. The magnetic head also prevents the Evans Torque Key from rattling during play when left on a drum lug for convenience. The key's torque handle can be set to a desired tension, so when the lug reaches the preset tension it will release, making for even tensioning and helping drummers attain more accurate tuning.
