DW s quick-release cymbal stand wing nut has been in development for quite some time. The spring-loaded mechanism is smooth and precise, allowing drummers to either thread their cymbals on in the traditional manner, or skip the process with a pinch of their thumb and forefinger. The QR Drum Key Wing Nut has the same innovative functionality with a twist: an integrated drum key for those desperate situations. Now, drummers can always have a drum key AND cymbal wing nut with a top cymbal felt handy. The DWSM2345 also comes as a 2-pack.
