      I just bought a used Santa Cruz B/PW.

      The instructions tell me I need a 5/16 “thin walled” socket. I haven’t been able to find one anywhere.

      Does anyone have a good source for one? Thanks

      Standard deep socket with ¼” drive should be fine – avoid sockets designed for larger drives, and sockets designed for impact as they tend to have thicker, heavier sides.

      Lots o’ SCGC guitars! But never ask which is my fav

      Thanks all for helping out with this. Here’s some FYI’s to fill in the gaps. We found that the original 3/8″ Truss Rod nut was not close enough to 10mm to satisfy our European customers, whereas 5/16″ and 8mm was a perfect match! This was a nice contribution to world peace so it became the standard about 2011. If you’d like to be sure regarding your personal guitar; go to and using your serial and model number as reference you’ll see what size nut is on your truss rod.

      The thin walled socket is only recommended to keep it from binding between the old 3/8″ nut and the wall of the access hole. With today’s 5/16″ nut there is ample clearance with no chance of binding, making any standard issue socket appropriate for the task.

      Best, Richard
