source for left hand thread nut and bolts

I need one or two left hand thread bolts with nuts.

These are very hard to find online -- finally came up with this from McMaster-Carr:

Grade 5 Steel Left-Hand Cap Screw, 3/8"-16 Thread, 2" Long, Fully Threaded $5.98 each (Ouch!)
Left-Hand Threaded Extra-Wide Hex Nut, Grade 5 Steel, 3/8"-16 Thread Size, $7.29 pack/10

Anybody have one or two they would be willing to sell me? I could use anything down to 1/4" by 1 1/2".

Well, not 'Fasterthenal' same Gr5 is only 1-1/2" and $14.56. Makes Ma-Ca look much more reasonable though.
Not surprising, often finding them better priced for odd but mass produced items.
