Oil Pan Drain Bolt head size?

2010 JK...did a search, no luck. With a flashlite I can see metric strength markings of 4.8. on the bolt head. Looks abot 1/2" in size so I'm guessing it's either: 12, 13 or 14mm?? What is correct oil pan drain bolt head size?? thanx.....

Transmission/Xfer case drain and fill plugs. These appear to be a special 5 point type of plug (?). Can one verify 1) the location of drain and fill plugs for each the 6 speed and xfer case AND what are the sizes/types fo plugs and the ensuing "tool" that is needed to open them? thanx...

According to the write-ups on a couple of other sites it's a 13mm bolt.

yep, 13mm. I changed my oil 2 months ago and had to go buy one this size since it isnt all that common and didnt come with the 2 socket sets I have.

I actaully have 3 sets, two from tractor supply 3/8 and 1/2 inch drives and one from autozone 3/8 drive (dont remember the brand) Not one of my sets included a 13 mm. I had to go and buy one at tractor supply individually.

My 07' is 13mm , I bought a Snap-on 6 point comb wrench just for doing the changes ..... no chance of stripping the plug head .
On metric tools .... some sets are more European 12mm,15mm,18mm .... some are more Asian 13mm,16mm no 18mm . And some just don't make sense ..... I bought shallow and deap sockets in 15mm & 18mm in 3/8" & 1/2" drive in hand tool and impact along with combination wrenches to keep in my Jeep tools . I also bought "Flex-head combo gear wrenches ..... kinda over board but being a life long tradesman I never pass up a chance to toolup if there is need ... and usually over kill it ...LOL !

JK Lug Nuts are 19MM...

I think they exclude popular sizes Like 13MM as a cheep attempt to get you to buy the missing socket for an extra few bucks = Lame.
