Using torch to loosen bed bolts

I've dealt with rusted in fasteners many times. Liquid wrench is very good, pb blaster, wd-40 would also help. You don't want liquid wrench in you eyes so safety glasses should be used. I would suggest to begin a regiment of spraying the bolts, let it soak in. Repeat every couple days for at least a week. I like to mark the bolt with a sharpie or scribe so once you start torquing on it, you'll know if its moving or not.

Torx isn't ideal, perhaps a button head hex bolt would be better. The back and forth method previously mentioned will sometimes get it. An impact driver, not an air impact wrench, gets most to start moving.

Something I've seen but never used it. You stick this thing in an air hammer, put the socket on the end, there's a handle to pull on. As it's hammering, you pull on the handle to loosen the fastener.

 

I do aircraft maintenance we can that a screw knocker. Very every effective getting shit out before it strips. It’s failed me a lot but it’s my last resort before drilling deff worth a try

 

Have you ever used one of these?

I’ve heard about them, not used one myself.

 

Not exactly but very close it’s got it’s wrench (for lack of words) built into the knocker.
But that and an air hammer and I doubt there much you won’t be able to get apart lol

 

LOL
By the level of your rage, I have a gut feeling u r a Minnesotan as well.
It takes a lot of patience to work on old cars in Midwest.
I was just trying for a short cut (torch) and hoping someone would say "it's OK go for it" but so far no suck luck,,,lol

 

Weld a nut to the top, the heat should also penetrate the rest of the bolt some.

 

Today was my 2nd day working on it. As you said, I am planing to do this for a week, spray and try to break it loose, and repeat.

 

Before I put a tool to it, I repeatedly spray it. As in spray, 2 days later spray again, repeat.

Al little heat would be ok. Park it in the sun. Or a butane pencil soldering torch, just to the point it begins to smoke.

A stuck torx bolt, you only get so many attempts before screwing it up. If you already tried torquing on it, I’d wait for the penetrant to penetrate really good so the next time you put a tool on it, it’s gonna come loose.

I think that air hammer tool is called shake and break.

 

spray the threaded side with penetrating oil

AND TIME
It took me about 5 days to get them out, Spray them, try to move them and spray them down and let them set.
2 foot breaker bar and 1/2 impact gun helped move things along...
Just dont get in a big hurry

I found the bolts near the tail gate where EZ to get out.

 

Spraying them never seemed to help me. Got most out w/ a breaker bar but had a couple that wouldn't budge. I found the biggest impact gun I could and they broke free like they were never even stuck.

 

That's what I had to do with mine. I broke out The Bruiser and it backed them right out.

 

Could try using manual impact tool. Just get the torx in bolt and pound on it . So you actually shocking and turning at same time .Also since pounding on it less chance of torx slipping out and damaging torx bolt .But at same time easier to snap cheaper torx sockets .
I have a Mac brand and was solid . Not sure about some of these ebay ones .
