Like ger21 said. These are actually 1/2"-4 threads, however there is 8 threads per inch. You could say that there are (2) 1/2"-4 threads, 180 degrees apart.
sendkeys: Thanks for your good wishes, I hate it when people jack up the s/h charges to make a few extra bucks. It costs me .83 cents to ship 4 of these in the US + .50 cents for the bubble mailer, I have no problem covering that!
