Stripped Bolts - Toyota Yaris Forums

why? · 10-28-2009, 04:59 PM

So I finally got a wrench that actually worked, and the only two bolts left to do are the ones I stripped yesterday. I'm going to give them one last try, but how do I get them out if they are completely stripped?

Oh, and another question, I can't seen to figure out how to get the top of the seatbelts out. I don't want to push too hard on the plastic, because I don't want to break it. Is there some trick I don't know, or is it simple pressure?

Get a wrench made by Snap On in the size that fits. They will work on the heads of nuts/bolts even if they are totally rounded off.

Use a dremel tool to turn the cap head into a slot head and use a big screwdriver.

cutoff-wheel, chisel, ez out? or, you can head to autozone and pick up a set of irwin extractors for about 20 bux. not bad seeing as how the snapon set which is made by the same company is almost 200.

I'm not sure what size. I just got done looking at it a few hours ago. I know there is a set you can get at sears or advance auto parts called bolt out. I'm going give it a try and let you know if it helps.

I was wondering some cars had reverse thread. Do you know if that is the case?

severous01 · 03-31-2010, 05:10 PM

well, the easy thing would be vise grips for me depending on where they are and how big...anything up to about 15mm

or, drill and extract w ez-out, slot and use a freakin massive screwdriver...use a chisel and tap in reverse direction, like you're trying to back it out with the chisel...

sometimes you can just hit it really hard in the center with a punch and it makes things easier to back them out.

but like mentioned above, use a high quality 6-point wrench or socket made by snapon mac or matco. they have what's called flank-drive. it's set up to touch on the flats of the bolt, not the edges like cheapo wrenches and even craftsman.

Yes..I just use the bolt out and it works really well. I think the bolt however messed up the some of the threads though. I'm going to try a shorter bolt and see if it works, but new belt is on.

reverse threads are usually only used on waterpumps. or fan clutches. i can't really think of any other application where one is used on a car.
