Bolt heads rounded off

Cheap 12 point socket can round a bolt too!

I have done 3" spacer lift on my buddies Tundra and I haven't had problem with any of the bolts.

There was no locktite on the factory bolts on his Tundra.

 

Get a set of these Vise grips. They will absolutely NOT slip.
Second. 12 point sockets are for square nuts so you f'd yourself there. Always use a 6 point.
Third apply a little heat and you shouldn't have any problems.
This bolt has sooo much working room, you think your pissed? try removing rounded or snapped bolts in tight locations! Youve got it pretty easy right now.
