Well ... assuming that your screw was a 1" long one, and looking
in the MSC catalog for the 8-32 size which you say you are using (and I
would suggest 10-32 anyway for that), the prices for a box of 100 range
from $5.64 for the "import" (which is still pretty good from MSC) up to
$16.87 for the ones made by "Unbrako" (which are really tough steel).
....
I think so. What I have not found is your newly-posted photo
(though the URL might be in some other branch of this thread). I could
not find it by working uphill from the previous URL, as indexing of the
directories is turned off.

Man - thanks for the absolute WEALTH of information !

Here's the URL: http://www.waycoolgear.com/ebay/screw_in_bushing.jpg

Anyway, I am copying your post to my notes and will be referring to it
frequently, I am sure!
Thanks!
