SMA connectors

[reubj]

Does anyone know a source for the jam nuts used on SMA bulkhead connectors. It is a 5/16 hex with 1/4-36 thread. None of the connector suppliers want to sell separate nuts (sounds like a conspiracy). I've checked all the usual suspects (Keystone, etc)and have struck out. Any help is appreciated.
Thanks.

Have you tried McMaster-Carr? If they don't sell it, you don't need it.....

Thanks for the response. I tried McMaster-Carr. They don't have them. I did find an AMP part number for them but haven't checked on availability yet.
