Wanted 7/8" NF left hand thread nuts
 

I'm looking for a pair of 7/8" NF (14 TPI) left hand (backwards) thread nuts for a project. Does anybody have any or can recommend a source for these somewhere in Canada-ish that will sell me two?

From the US web site for fastenal, but you might want to take the SKU and call your nearest outlet to see if they have it. Oddly enough the US site says there is stock in Leamington (Ontario).

Or try McMaster-Carr.

I would also have included McMaster if I believed it would have helped, but they have refused to ship to Canada or even to a US address if they believe the product will eventually end up in Canada (for example, if your credit card has a Canadian billing address). Maybe their policy has changed.... but I have a long memory for unhelpful suppliers.
