Unlike the traditional wing nut, Slick Nut doesn't need to be threaded on/off. Simply hold in the fastening button, put on cymbal stand to desired tightness and release button. The Slick Nut can also be used as a theft deterrent by simply tightening the hex set screw on the side of the body. This makes the Slick Nut non-removable. 8mm thread size.
