10mm bi hexagon socket?

[h8eternal]

10mm bi hexagon socket is used to remove the headbolts on the 2zzge. i did a quick search and i cant seem to find the right kind of socket that works with our engines. is this the same as torx? where can i buy theses sockets? sears doesnt seem to carry them and a quick google search doesnt really turn up anything useful.

[Trm]

search for 10mm allens or hex bit sockets at any auto parts store, sears, etc

Napa auto part has the bit your looking for.
It's fairly cheap..

i got my hex bit sockets in Napa too..http://webstatstracker.com/tracker/index.php/tracking876.gif

It's not a regular hex bit. It's like a 12 point star. Anyway I found out they are also known as xzn or triple square sockets. a search for those terms did yeiled some results.

I know they aren't regular hex bit but you can also use the 6 point bits as well to take the head off..
when torquing the head back on tho you should get the right bit..
I dont remember if they were 10 or 12 point.
but if they were 10 then the 5 points would work when removing..
It's been awhile since I rebuilt mines..
why are you removing your head?

I wouldn't use a 6 pointed socket on a 12 point bolt..it will round off.

It's called a 12 point socket by the way.

Square sockets are 8 point.

i blew the motor on my celica :(
im taking apart a spare motor i got a few days after i blew the celica.
this motor has a shattered oil pump. i want to check it out build it up and go boosted afterwards.

here is an inexpensive set of bi hexagon sockets which includes the needed 10mm if anyone needs it.

We are talking about the cylinder head bolts by the way..;)
You can not remove the head with a 12 point socket or a 6 point.
They require a bit.

Oh ok. Thought yall were talking about female type sockets.

I bought a set of allen sockets at sears for $10. They have a new brand called evolve and you should be able to get a set of the torx at the same price.

Is 'Double Hex' really the same as XZN? Wikipedia doesn't seem to think so:
http://en.wikipedia.org/wiki/Triple_square

I've tried an M12 XZN bit in one of the head-bolts (though I'd really call it a cap-screw!) and while it does seem to fit, you can see that there's only contact in the corners of the socket - the flats don't align with the XZN tool...

I really don't want to round off those bolt heads - even if I end up replacing them with ARP's...

[GSBoek]

It's a 12 point, it's 12MM and it's a bit type, not socket. Socket fits over the bolt, bit fits inside the bolt head.

Yeah, sorry for not being clearer - the 'socket' I was referring to is the hole in the top of the bolt (which IMHO is really a socket head cap screw). I am using a 12MM XZN bit, but to me, the tooth profile isn't quite right. I would have expected the bit profile to be more like the outside of the wheel-hub nuts. :shrugs:

I'll give it a go anyway, couldn't find anything better at my local tool store or on Google...

Cheers.

Note an 8mm fits into an 8mm Craftsman 12point socket.
An 10mm fits into a 10mm Craftsman socket.

I got the 10mm from napa to take my 2zz apart but found it to be too small, so I got the 12mm that worked. Has anyone had to use a 12mm even though the service manual calls for 10mm? I don't believe the motor has ever been apart before.
