Not only that but be careful.

Earlier Camrys have JIS heads on the 6mm bolts that hold the idle air control valve to the TB. I cammed them out with my Phillips and then did some reading. Reading said get the JIS drivers or you'll cam these out.

I have an ancient reed prince screwdriver with a wooden handle that has always been my go to instrument for JIS screws.

Now, I have at least 50 Phillips screwdrivers of all shapes and sizes along with probably twice that many bits that fit screw guns and things like that and I root through those to find the bits most suitable. Usually I can find something that’s a happy fit for these godforsaken JIS screws.

Bristol Spline, baby!!

In my yoot, I spent too many hours running one of these: a 2-1/2" drive IR impact gun. That hole in the top/middle is a threaded hole for the big eye bolt to hang it.



It'd hang from a crane and took a minimum of 2 men to run it.
I'd feel it in my bones for a week.


Biggest impact I ever operated was a 4" drive, at the Huntington beach edition generating plant.
We used it to break the head nuts loose on a boiler feedwater pump. Took 4 men to operate it and it had a dead-man's trigger.
Well-named, they're illegal now after a guy got killed by one.

After a couple hours of use the drive square snapped and we had to use an air-arc to cut the remaining nuts. None of us were good enough to scarf off the nuts without getting into the threads, so they brought out an edison old-timer. he was an artist.

Whenever I'm doing something I don't like, I remember days like that and it seems not so bad.

Oh and it was loud too.
And cold. Hands would freeze up from the air exhaust blowing right on them. the darned exhaust would work loose and turn from the vibration no matter how tight ya got it and always ended up blowing on your hands. Senior guys knew not to get on the trigger side.
Newer guns have a twist throttle, lots safer.

It gets delivered to the fastener with a forklift. Wow.

I'm surprised those bitty pipe handles didn't just snap right off every time.

I once used a two grip 1" drive on tractor/trailer wheels. (thought it was bigger than that actually)
That little thing was a loud enough beast.
