Odd Question - RAW Adjustable Hamsters - Thread Size?

[Bramezy]

On the off chance does anyone know the stock screw and thread size for these older adjustable hamsters? The actual threads in the wood, or the nut insert. I don't have it handy with me and need to order an insert.
Thanks

in my old heavy silver hampster from Raw the set screw and insert are 5/16-18 coarse. Martin may have used different ones at different times. Just make sure your set screw and insert are the same size.
