The PinchClip from William Feldman Studio is a fast, secure and simple accessory that was designed to replace conventional nuts and wingnuts on many types of threaded drum hardware, including cymbal tilters and hi-hat clutches. The stainless-steel flange flexes when pinched so that the holes in its overlapping arms align�� allowing the clip to be quickly applied and removed�� yet the specially designed arms securely grab on to any threaded device when the finger pressure is released.
