Does anyone know the screw size for Yankee Hill Machine's low-profile pinch-style gas block? (YHM-9384) The screws they sent with this thing don't seem to match any of the allen wrenches that I have. Either the wrench is just a little too big or too small to drive the screw. And one of the hex sockets is cut off-center, leading me to think these are cheap junk screws. I'd like to get better replacements, but don't know what to buy.
Or maybe I just don't have the proper wrench size..? The instructions don't say what to use.
