Does anyone know the proper name for the type of thumb nuts used on the surefire M49 weapons light mount is, and where they might be purchased?
Surefire wont sell them. I would like to buy some and swap them out on some of my other mounts.
Thanks

Take it to a hardware store and they will determine the thread count and head size.  Most thumb nuts use a 13mm hex nut outside size, but there are many different thread patterns for attachment.
