New Schallers? No. Actually the strap pin part of new Schallers is the screw head, for all practical purposes. It's all one piece, and has a small hex key hole down inside the strap pin, for screwing it on the bass. However... I replaced the Dunlops on my new Serek Sacramento Bass with Schallers recently. Other than having to drill the pilot hole a little deeper (the Schaller has a longer screw part), I didn't have to do anything else. I just made sure the screw started in the existing threads in the wood, and screwed the thing down with a little hex key. Easy-peasy...
