studs for sling/bi-pod/etc

[AreWeNotMen?]

So I am looking for a few 10-32 threaded studs, but can't find them locally and I don't want/need a 20-pack from Brownell's! I need one or two with 1/4" shank, and couple with about a 3/8" shank (bipod mounts for my IWI Tavor SAR-21's). I thought they be simple to find...I was wrong.

Got any ideas?

Or a few lying around you'd part with?

Thanks.

The last time I got some was on amazon.
I needed a curved and a flat mount.
With Prime it ended up competitive with others.
