I'm a newly registered member who's been lurking around here for some time. And I signed up just to answer this question.
For all the overly ****, like myself, I measured up the bolt head. It is positively a 16mm. A 5/8 obviously works but per ISO/SAE specs, it's a 16. My bolt head measured 15.99mm on one flat and 16mm on the other two. A 16mm must measure between 15.73mm and 16mm. If it were a 5/8", it needs to measure in at a minimum of .612" to a max of .625". Mine measured up at .629, .631 and .6315........ too big.
By the way, I searched this question because I was too lazy to slide under the truck with two wrenches in hand. I just wanted to grab the one wrench......... isn't that about the saddest thing you ever heard?
Have a good one,
Pete
