No it is not.
It's a standard thread not reverse threaded. Same with the automatics flex plate bolt and manual transmission's pressure plate bolts.
No, the crankshaft pulley bolt on a 1999 Toyota RAV4 is not reverse threaded; it is right-hand threaded. This means it tightens clockwise and loosens counterclockwise. When removing the bolt, it's important to use the correct tools and techniques, as it is typically torqued to a high specification.
Standard.
No, but it is very hard to get loose.
I own a 1996 bonneville. The tensioner bolt is a reverse threaded bolt, (tighten to loosen). Hope this helps. DCC
NO, IT'S JUST VERY TIGHT.
No but they are torqued on at 125 to 130 ft. lbs and as a result, very hard to get broke loose.
To remove a harmonic balancer, you typically turn the harmonic balancer bolt counterclockwise (to the left). However, some engines may have a reverse thread, so it's always best to check the specific service manual for your vehicle. Ensure that the engine is securely supported and that you have the right tools for the job.
Yes, the bolt that holds the harmonic balancer in place on a 2001 Chevy Malibu is reverse thread. I learned that the hard way and stripped the head of my bolt down to nothing. And the bolt is almost impossible to find, because they no longer make them.
It should be regular threaded "Lefty Loosey." If you are having problems getting it loose, try an air impact. If that does not work try hitting the side of the socket while the air impact is hammering. If that does not work carefully heat up the bolt head with a torch and try the impact again.
They are threaded the same way as SAE bolts; both have applications that have reverse or "left-handed" threads.
