Loosening Rusty Bolts

Don't forget here guys that if you have a part that you can get in a large trash can, electrolysis can be used to remove the existing rust making your part come apart much easier.

My current favorite spray is 3in1. It works allot better than PB, but I've never heard of Kroil. I'll keep my eye open for it.

The torch works good if you have one, but if you pull it out, you might as well just cut it off. I doubt you want to save this bolt anyway.

My 4 1/2 inch grinder has taken off quite a few nuts and bolts too.

Yesterday I had one that I couldn't get off with my impact wrench. So I switched from loosening it, to tightening it. Back and forth until the bolt snaped off.

A breaker bar with a pipe on it will take, or break, off anything. You just need a solid head for the socket a GOOD breaker bar and a long pipe to put over the breaker bar. If one pipe doesn't do it, you need a longer one!! haha

I've had some pretty long pipes on my 3/4 inch Proto breaker bar. I have the Proto becuase I've twisted the heads off of cheaper ones.

Is the bolt hardended? You can also drill right through the middle of it. Start out with a small hole and work you way up. It will come out before you get too big a hole.

Good luck and let us know what worked for you.

When swaping roll cage from my Jeep I had to use 4 1/2" grinder as the wrench:)

There was no other way - I hate torx head bolts.

kroil is great stuff, works as a penetrating oil or general lubricant. i think it is manufactured in nashville tn

Quick question while we are talking nuts and bolts; would a grade 8 nut and bolt rust slower or faster than a regular grade 2? I really don't know, but I'd bet that they don't rust at the same rate. Anybody know?

As to which penetrating oil is best, it is my running joke here that everyone wants a different one.

Guy A comes in with a can of green stuff in his hand and it is

"THE ONLY one that works,,,, get rid of that other stuff"

Guy B comes in the next day with blue stuff in his hand and you guessed it,,,

"this is the ONLY one that works,,,,,, Get rid of all that other stuff"

We keep about 6 different brands around so that people can rotate as they find what they like, and run into various situations.

At my house, Kroil, PB blaster, Yeild and MMM are on the shelf, and as someone else said, the Plasma makes them all look pathetic.

Different grades rusting.

I think you would find that the different rusting would result more from the quality of the bolts in question and what particular surface treatment they had and how they were handled as opposed to the particular base steel composition of the bolts.

There are several good penetrating oils out there, but Kroil has some name brand recognition in my industry. Plus, I like the smell of it! I buy it by the case via the Kano Labs internet site. I barter with it or sell it to my pals, who also seem to prefer it.

Does it have addictive scents added to it?:D
