11 and 13 mm hex bit sockets from Snap On?

[MadMark]

I just missed out on a Snap On hex bits socket set.
It had 11 and 13 mm 1/2 drive hex bits along with the normal sizes.

I thought the common large sizes were 12mm, 14 mm and 17mm.
What on earth are 11 mm and 13mm hex bits used for.

Heres the link

Also, are the Snap On hex bits that much stronger than all the other makes?
Armstrong hex bit sockets have a better price, but since they are made by Danaher, I suspect they may be no better than Craftsman.

no one has ever asked for one from me and I have been doing this for over 8 years.

I bought a 4-14 set in 3/8th because i saw no use with what i do for the 1/4 ones in the 2-10 set, and my dealer was dumbfound he was like i've never heard of this set.

13mm fits brass injector inserts on early fuel injected Volkswagens (impossible to find when you need one).

Thanks, could you use a 1/2" SAE in its place, or would it slip and strip the injectors. ( I could see it being easy to round out brass )

Also, I'm sure a 7/16" would do for 11mm.

Yes, 1/2" fits; filling out the hex socket set with the proper tool, however, would be very satisfying!

13mm is also used on some VAG TDI fuel filter housings.

11mm, no idea.
