You just need a 12 point socket. a small one like 1/4" drive or 3/8" drive. Small enough to get in there.

If it's an internal headed bolt then it's not a Torx bolt, it's a 12 point spline, also called a triple square.

I've never heard of Toyota using Torx pattern for head bolts, Searching on the net indicates that the tool required is the same as the one for the 3S and I know ituses 12 point spline.

So while a T55 torx bit may fit, it is probably not the right tool for the job and in reality is no better than using an allen key, in fact it's probably worse.

Torx bits have the wrong tooth profile and are only 6 point, the bolts in question shold be 12 point.

Anyone got a picture of the bolt in question so we can identify the correct tool for the job.

The Blacktop ROM mentions a 10mm double-hex socket in its list of required tools.

About as good a job as a surgeon using a rusty razorblade compared to a scapel. Which would you prefer?

would be alot better than a allen key

Guess again, it's the wrong size, the wrong tooth profile and at best would point load the bolt, at least the allen key will work on the face of the cutout and spread the load far better than a Torx driver :roll:

Still the question asked was what is the right tool, not what is the next best thing and the answer to that is a 10mm 12 point spline/double hex/triple square, not a Torx bit or for that matter an Allen key.

umm yeh i did say it wasnt the right tool.
yes the 12 point hex (or what ever you may call it) is the right tool. i have one for my 4e and 5e. but since its a diffrent size and the torx is easyer to come by. i brought the torx bit witch did the job. for a one off it works.

i could state that he, or no one for that matter. asked what the right tool was. but im not that picky...

i'd say more like a surgen using a fresh stanley knife blade. still works, but you just need a bit more skill :D

Nah, an Allen Key is more like a Stanley knife, the Torx is definitely a rusty razorblade :wink:

As can be seen from these drawings the Torx driver is a poor fit, whereas the Allen key is much better (though still not the right tool)

Just lucky I guess, if the bolt was siezed then I can imagine the oaths being uttered at those who said that the Torx bit was the right tool for the job.

That said, I'd liken anyone who sells you a Torx bit for this job to Dr. Nick. Then again the average Ripco employee isn't the sharpest knife in the draw :lol:

Edit - thanks sark.inc, the link to the correct Ko-ken tool
