I can do 40 NM with a t-handle wrench. I admit I'm a big guy, with
good hand strength, and have tightened lots of fasteners. with an L
handled key, it's pretty easy. My long one is 15 cm long, so you need
to put a force of 266 N on the end of it. so put a bit less than 30
kilos into it. assuming no muscle, that's a bit of a grunt, not that
hard. Put a socket on a ratchet, and you can have a big lever, no
problem.

What you'd want is called a 'crows foot wrench', a socket with an open
end wrench on it.

Tight pedals dont' move, which means they don't make noise.
