socket for a toyota headbolt?

[greasemonkey44]

i pulled the head today on a 2001(?) celica; i got the bolts out using a triple square bit
but i heard asian cars use double hexes for the head bolts!
i dont mind buying the right socket at all; i just wanted to make sure i didnt get the wrong size....or that the bolt might be a triple sq

Correct.

Euro cars maily use the 12 pt triple squares while japanes cars mainly use the double hex. (there are variances out there due to globalization and technology swapping/crossover)

Looks close but different heads .

You'll just bugger the heads if using the wrong tool.

Can you not use a regular hex? Are the points too small to handle the torque?

The difference:

Bi-hex/double hex:

Waaaaay different.

Well, if you go back to math 101, the triple square bits use 3 sets of squares using 90 degree corners to grip the bit.

The double hex uses 2 sets of 6 point bits meaning they grip at 60 degrees at each corner and not 90 degrees.

Dunno how your math works, but to me, that's a deal breaker. (BFH excluded)

Will a single hex work? Well with enough heat and coaxing, maybe yes and maybe no.
If your engine, would you trust it?
