And when you do install a crank, it's one of the few bolts on a bike that you SHOULD do up WAAAAAAAAAY tight. Get a nice long-handled 8mm allen key, use the crank arm to lever against (like you're repeatedly bringing the big and little hand together on a clock from about 7.23 till they both point at the 6 ?!?).
There's a point where you think "this must be tight", but if you keep going, you'll reach the REAL tight-enough point a bit later.

How unscientific was that?
