    The Mosin bayonet screw is 32 pitch and the od is .256 my question is what kind of tap and dies do I need? Is this a specific European size? I have a 1/4 x 32 tap and that chases the threads, but the 1/4 x32 die is no way going to chase the screw. Anyone have anything to offer up for help?
    Thanks in advance.

    I use a thread shaping file myself. There are only two common shaping files, metric and SAE. Thread shaping files are good for removing locktite. If you have to replace the screw numrich or eBay should have it.
