Hi Joe,
Thanks for the lead. Wow, McMaster just seems to have everything. Wouldn't it
be nice to be able to just stroll through the isles?
Anyways, looked at the available stock. They seem to only stock "Temper: Hard
(H04)" for the sizes that I'm interested in. Just how "hard" is H04? I need
to be able to put either a 90 deg bend or a twist (depending on where I put the
ANL current limiter block).
Thanks,
/\/elson
