[sdiy] Seeking for black Moog system wood screws..

[Jean-Pierre Desrochers]

I'm looking for the 'same type of ' black wood screws Moog used for modules
in their modular systems years ago..
Here is a picture of some:

I also noticed that Hammond used the same type for their B3 metal face plate
with the Hammond Logo:

Is there anybody that would have a good link to buy some today?
Please note they are not TRUSS screws like these:

or these:

Those I'm looking for have a flat surface at the cross center of the screw.
Any suppliers ?

Thanks
