Unlike the traditional wing nut, the Slick Nut doesn't need to be threaded on or off and won't loosen or fall off while you play. Simply hold in the fastening button, put Slick Nut 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, a great feature for drummers who have to leave their drum kits unattended for a period of time. The Slick Nut comes in 8mm, the most common thread size for cymbal stands, with top cymbal felt already attached. Hex key and replacement felt included.
