delete please. problem solved!!!Bolt size question. In between sizes?

[munepit]

Hey guys, hope you can help. I have a couple header bolts loose. I can't find the correct size socket. Its bigger than 3/8 and smaller than 7/16. Also, bigger than 10mm and smaller than 11mm. The bolt has about 10 points on it. Any ideas? Thanks in advance!!

3/8 = 0.375
10mm 0.394
11mm 0.433
7/16 = 0.438

There's nothing in between those values....maybe it's just a little crusty, and a smaller wrench will fit if you clean the crud off first??

It was 3/8. A socket didn't fit but a wrench fit. All good now. No leaks!!!!

I only use 6 pt sockets but it is nice to have a few 12 pt ones since they usually will fit on crusty bolts/nuts

The bolt was brand new. You know how tight of a fit it is on header bolts.

Mr. Goodwrench gets it done.
