no prob at all. If you want to extend it, you might be able to get a coupling nut in the right size. Then I'd use a jam nut on each side to secure it well. Look up coupling nut and you'll see what I mean. McMaster doesn't seem to have 12x1.5 unfortunately... :/ I can check locally if you'd like. We have a huge screw/bolt place nearby and I have a rather large order to pick up soon...
You can also call McMaster and explain what you are looking for. They are absolutely amazing. Bar none.
