HF tools are a wonderful alternative for the occasional user. It is idiocy to buy professional grade tools for once in a lifetime jobs.


I disagree, they are simply junk and as mentioned needing to take the tool apart to grease so it wouldn't fail. $93 for a quality DeWalt is NOT out of line IMHO.

Also look in the mirror, support someone like me or a Country that wants to dominate us.

As mentioned once you own one of these tools you will find your self using it.

Speaking of Harbor Freight, I was given a full set of 3/8", 1/2", and 3/4" drive sockets from HF when I was 18...suffice to say that was well into the last century. Have used all of them over the years to one degree or the other...3/8" stuff a bit more than the big stuff, but with a few rebuilt trailers, couple of big trucks, and the infrequent dozer and tractor over the years, they've all seen occasional use.

....none have ever broken and, while I've lost a couple of the sockets, the ratchets and breaker bars are going strong more than 40 years later.

Did the power tool destroy, or the fact he turned the bolt?
IMHO, it was his lack of understanding of how nut/bolt should be works. To loosen or tighten the fastener, turn the nut. To get it off on, does not matter as much.


With an impact wrench it is not possible to determine how much torque you are applying so that you can oppose that torque with the wrench on the other end. I believe that he did in fact use the impact on the wrong end but hand tools are the better option IMO.


With rusted fasteners, the impact action will break the nut loose with less force needed to hold the bolt. If the bolt starts to turn, put more force in the hold, just like working with hand tools. OTOH, often when turning a wrench much of the force is pushing sidewise, not rotating.

OP, on the bolts you have already spun, not likely to have a issue, unless the sleeve is spinning in eye of spring, but I would run the nut out to flush with end of bolt, then tap it with a hammer. If the bolt does not move, put a oversized socket on the head of bolt, hold it in place with your 12lb hammer head. Then with your 3 lb, hit that bolt like it is a 30 YO wanting to date your teenage daughter. Less likely to bend it that way then failing around with a little hammer.

thanks all. I was holding the back side with a wrench while trying to use the impact, but I did have the impact on the outside which is the bolt in this case.

I could have those bolts off with a grinder quicker then you can find the right size socket [emoticon]



I have cut off many bolts in my life. Most with a torch but many with a grinder or cutoff wheel. You must have a whale of a cutter, or one disorganized toolbox...

The thin slitting disks really do cut like butter.

It was a figure of speech, which I hoped most would get it, but apparently not . [emoticon] I don't mess with those rusted frozen bolts, I grab my 4.5" grinder ,and cut them off, what on a 1/2 bolt 30 seconds per bolt about 5 minutes more or less those shackle bolts are off. All those great ideas are okay penetrating oil , impact wrench etc , but not for me.

I just received the grinder with the case (DWE402K) and it is a "USA made" unit. That's was a bonus. It's hard to find the US made DWE402 these days.


Unfortunately too many companies use the term USA Made when really it’s USA assembled from off shore parts. Sad but true

Most importantly, before you start cutting off nuts or bolt heads, think about what is stuck, what is spinning and how you’re going to complete the disassembly. Or you might end up cutting off an end that will make the bolts more difficult to remove.

Cut off wheel or SawzAll for the win.

Working with little stuff like a TT, likely 3/4 wrench or smaller, and 10 years or less old, put the impact on the nut, wrench on bolt. In seconds, ready to knock it out. The biggest chance of damage will be with the hammer. Earlier I told how to avoid that damage. Once the bolt is cut off, you need a 3rd hand if, unlike in the OP's case, the bolt is rusted in place.

OP, something you need to think about. In times past, I have used a acetylene rig to cut off nuts and saved the threads it screwed on. A cut off wheel to remove bolt head is not a problem, if I have room to work. But I have worked with that kind of tools all my life. A grinder, cut-off wheel or even a Sawzall can cut the softer and thinner steel of the hanger faster than it will cut the bolt. Are you sure you will have the skillset to cut the bolts without damaging the hanger? And even more important, working under the trailer it would be easy to cut you, and that kind of cut hurts like bell even if not serious.
From your post, your bolts are not rusted in, or they would not spin. Likely the only rust in your way is on the threads between nut and end of bolt. Use the wrench to spin the nut instead of bolt. Should be a piece of chicken

OP's question was "How to", not HF vs other brands.
At any event hope he got it done and on his way [image]
