Hi Rob,
I’ve seen bolt heads with N A T before, but I have no idea what they were used on.

The charts I found don’t list it.
Seems NAT would stand for National ?

Where did you see this marking ?

Hi Chris,
They are from the original tie rod adjusting sleeve clamps from my GTO. They're a bit crusty from the years in the Midwest winters until it went off the road in 1972.
