I think they are called barrel nuts. Do you know the thread pitch of the reset shafts? It might make searching for it easier.
Does anyone know a company that sells just the screws? I seemed to have missed placed one. All the companies I have found want to sell me the knobs and screws.Thanks
You might try taking the screw you have left to an eyeglass shop.They have a lot of small screws.
