Mihec thread question

[mulespurs]

I noticed the last time I went to cast some 45's out of my Mihec 68 clone that I had no setscrew in the sprue plate screw.

The screw that holds my sprue plate is there just not the set screw. Does anyone know the thread size of that set screw so I can get one?

Just measured one off of mine, it's M4x0.7. Might be able to tap it to the next standard size up as a metric set screw of that size is probably a custom order proposition.

Thank you for your support
