Torque question?

How the hell do you torque a bolt when you cannot get a torque wrench on the nut?  I am attempting to tighten my bolts on the lower articulating arm connecting to the swing arm, (1986 FJ). There is just enough room for a box wrench.  You cannot possibly achieve accurate results by torquing the bolt head, can you?  Any ideas to tackle this one without purchasing additional tools?
Thanks!

Search for a "Crows foot socket". Then search for "offset torque wrench calculator". It can be done.
The glass is not half full, it was engineered with a 2X safety factor.

Holy crap, Mark, I was just about to ask about using one of those gadgets!!  So, using a "crow's foot socket" throws off the torque specs... that was my next question.

How the Crows Foot (CF) is positioned on the torque wrench will affect the measured torque to the actual torque. If the CF is sticking o straight out then you have the wrench longer, and will generate more torque than the wrench indicates. If you stick the CF out the side then you really have not changed the length much and will get nery near what the wrench is set at. https://www.youtube.com/watch?v=tv_KHH55qdQ

Dean:

I know the fastener, that you're referring to. Just use two box end wrenches, and tighten it up good. It's a fine thread, high strength fastener M10, or M12. If you're really concerned, clean the threads really good, and put some thread locker on its threads before you thread the nut on the bolt. Cheaper than a special tool, that you won't be using that often.

For most nuts and bolts that aren't holding together critical parts of the engine, you don't really need a torque wrench, just common sense.

A little experience working on bikes/cars is of course also good.

I'd say the same.
