I have a new trailer hitch that requires I torque the bolts to 260 ft lbs! How in the he11 do I do that? Any advise?

weld it?Funny, your answer to everything is something you can't do.

Use an impact wrench or a long pipe wrench but for more accuracy, use a torque wrench.

FWIW: MOST 1/2" drive impact wrenches max out in the neighborhood of 100-125, with some capable of up to 150 ft-lbs... In order to get up closer to this 260 ft-lbs of torque, you'd need to use a 3/4inch drive impact...

SO to get this accurate, you'll need to Either;
A- Rent a 3/4" drive Torque Wrench, and appropriate socket (provided you don't already ahve this stuff... which it seems you do not...) -OR-
B- Use the following formula, a breaker bar and a scale, and of course an 3/4" impact socket, so you don't break the cheapie sockets... If you don't have a socket large enough for this fastener, use a HD box-end wrench, and a handle extension of sufficient length, to allow you to utilize a measureble amount of force at the calculated distance...

260 ft-lbs of torque, simply means that with a one foot-long wrench, the force applied at a one foot distance perpendicular to the wrench handle, is 260 lbs...

SO; It stands to reason that if you were to use a 2 foot long wrench, the force applied perpendicular to the handle @ 2-ft would be cut in half, to 130 lbs, to attain a 260 ft-lb torque...

AND... If you used a 3 ft wrench, you could cut that to a third of 260, or roughly 86 lbs force... A 4ft long wrench would require 1/4th of 260 lbs to be applied to the wrench handle @ 4 ft, or approx 65 lbs...

Hope this helps...:) ;)

Really? 150 ft-lbs...

I dont know what cheap junk youre buying, but my pnuematic 1/2 impact is capable of 450 ft-lbs @ 90 PSI. My cordless impact gun will do 150 ft-lbs

A good 3/4 (hell even a crappy 3/4 for that matter) will put out 3-500 ft-lbs on a low setting (if its adjustable).

Edit* FYI: Most store brand torque wrenches only go to 250 ft-lbs.

I have to agree I have 3/8 drive that will do 250ft\lb. If you lived in my neck of the woods I have acess to torque wrench that will go to 1000ft\lb. We even have technology to do 2000ft\lb if you wanted to try and snap it off.

That's what I was looking for! Thank you.

As for what OB1Jeeper said most 1/2 that you'll find cannot do 260. I'm assuming what he was meaning is most are stamped like they can, but won't. There's a lot of junk out there in the air tool world and it's almost comical their ratings. I always thought it was funny that you could find a Craftsman impact rated at 275ft/lbs for $150 and then they would have at the very same store a 400ft/lb impact for $39. What the heck? Well, it's because the 275 one is actually made by Ingersoll Rand and the other is some Chinese junk that lord knows how they measured that. In addition the cheap junk uses a lot more air. I have two compressors. A larger one in the garage and a 3 gallon pancake in my RV. I can actually take all 20 lug nuts off my Jeep with my IR2131 (the same gun you typically see at Discount Tire) without my 3 gallon compressor kicking on. If I was using a cheap gun I'd be lucky to get one lug nut off.

Anyway, with a good gun (and unfortunately there are in fact very few "good" ones out there), you would be able to do it. My IR2131 will do it (it's rated at 450 in forward position and I believe 650 or 600 in reverse).

I did a lot of research about 10 or so years ago on who made what impact for what company. What happened is I got my first compressor and my wife as a gift got me one of those Costco bundles of air tools. My brother in law came over with his Tahoe and wanted to rotate his tires. Granted his lug nuts were overtightened, but I could not remove 1 lug nut with this 275ft/lb gun. I refused to remove it by hand, so off to Home Depot we went. I bought a Campbell Hausfeld guy, I figured, "this will do it". Got home, same thing. So back to Home Depot I went and I bought their largest Husky gun (rated at 550). This did it with flying colors, used barely any air, and had a great quality to it.

I later spent weeks researching air tools as I wanted to know what I was buying. It turns out that Husky is made by the same company as snap-on (I don't remember off hand, I think it was Florida Pneumatic or something like that).

Shortly after this my buddy lost his pinion bearing on his d44 in his '78 GMC. The one that's torqued down to I believe 250 ft/lbs. We were stripping the axle and I didn't realize my compressor popped his breaker. It had 60psi in it and still ha no problem taking this bolt off. That's quality air tools for you.

During my research I've always wanted Ingersoll Rand tools. Even though the husky still functions perfectly and has never let me down I later replaced it with the 2131 1/2 and a 2121 (I believe that's the number) 3/8. The 2131 weighs about 4lbs (the husky was around 11 or 12) and the smaller version that I have (2121) is around 2lbs. They're truly the strongest 1/2 and 3/8 I've used and at the same time use the least air of any air tool I own.
