[dsg-hallb_rich] [EXTERNAL] Nuts

[Tyler Lemon]

Hi Marco,

Those nuts from McMaster Carr have a six week lead time.

Is the main specification that the nuts be for M3 screws and are ~2mm thick?

Dear Tyler and Marc,
we would urgently need thin (<2 mm) nuts to fit
the electronic board stack into the RICH panel.
With the one available in EEL125 (2.5 mm) the
connector mating is not good.

We would need 1500 pieces.
We found a possible model at McMASTER-CARR:
90370A203       $5.71 for a pack of 100.

Others seem to be much more expensive. I cc
Sandro and Dario for possible comments.
Thanks, Marco.
