Hard to find as a replacement part! Chromed, rectangular head wing screw fits Gotz and some other European bass endpin sockets. Save having to replace your entire endpin assembly over a lost or broken screw! Yes, these hard-to-find, specialized screws are crazy expensive, but much more economical than the alternative.
Need other parts for your Gotz endpin? We Gotz ya! Purchase a replacement, thread-on stopper AKA 'Everlasting Gotz Stopper' HERE, and even an entire replacement endpin shaft (it happens!) HERE
