[R-390] Panel Screws

[quartz55]

OK, here's the deal.  I can buy 250 of each and drive the price per set down to $0.71.  Postage and mailers will be the same, that's always the killer.  If anyone knows of a cheaper way to mail these things, I'm open for suggestions.  I've been using the padded envelopes, and they cost about $1.20 each and they can go as a flat, but that's pushing it.  I'm sure the screws wouldn't stay in an envelope, but if I could find a cardboard envelope, it may be able to go as a letter even cheaper, but since I worked in the PO for a while, I know you can't send this kind of letter through the mail processing machines, it tears them up and the screws will end up all over inside the machines.  If I could send them as a letter, it would push the price down probably by .50 or so, even if they're heavy.

The other thing is, the 3 bottom 6-32 flat head screws are for mounting the wiring harness on the back of the front panel.  I've been looking in the book, but can't find what the specs are for them.  I pulled one out of mine but it's only got a 6-32 x 7/16 with a small pattern nut.  Can someone tell me what goes on these things?  I would think there is probably a flat, spring lock and then the small pattern nut. Is there an external tooth lock under the flat head for those 3, or just the 5 for the chassis screws?  Then I could also supply those parts and I bet 9A5BDP needs the nuts and washers from the description he gave.

I think there's enough guys so far for an order of 250, and then I could keep supplying guys for quite a while, it's only about $30 for the 250 screws/washers/nuts.  That's the other thing, the 6-32 screws are 7/16, not 1/2, meh.  I hope no one has been offended by that.
