I am not sure I understand what is being asked for in this thread. Aren’t a “hex head” and a “thumbscrew” two different things?
If this is what the question is asking about, this is what I did to be able to tighten the L-Brackets on the degree bar.
I replaced the thumbscrews on the L-brackets with plastic 9/16” knurled knobs from MSC Industrial Supply (part # 06172308) that come with female metal inserts that are threaded to #10/32, the same threading as the L-brackets. Next I had the heads removed from one inch #10/32 socket-head cap screws, and had points machined onto the ends of the cap screws at 45 degrees to match the points on the original thumbscrews. Finally I screwed the cap screws into the plastic knobs with a little epoxy to make sure they stayed put.
These thumbscrews never loosen up on me.
