I just won an auction on the bay for a Fray brace. It is missing the original thumbscrew. My question is what type and size are the threads? Is there some type of available thread pattern that works? I could forge the thumb screw part but need help with the threads (I noticed on the Fray brace that I own that the threaded portion is pinned to the thumbscrew). Does anyone have any other solutions to this problem? Thanks for any help.
