What is the best tool to use to round off hexagonal bolt heads?

Question

... also can be used to transfer intense welding heat to the palm of my hand?

Answer 1

I prefer to use a cheaper crescent style wrench to round off my hex bolts. The best way is to use it backwards, so the force is mainly against the movable jaw and set slightly loose.
If enough force is applied, there is an added benefit when the wrench slips and you smash your hand into some large metal object, and you produce natural solvent in the form of plasma that sometimes helps loosen the bolt.
Eventually, I get the six point impact socket, put it in the impact wrench and actually take the bolt out. But not before I have all that other fun, of course.

Answer 2

Start with a pair of pliers and then since you may also use the tool for heat transfer change to vice grips. This combination will work well on bolts and the vice grips will do VERY well for the heat transfer.

Answer 3

Next Christmas ask for a set of some obscure brand tools that are sold on one of those home shopping channels.
You know the ones that sell a 10,000 piece set for $19.99
and if you act right away they'll throw in a SECOND set at no extra cost to you!
Those really cheap tools are wonderful for rounding bolts and the like.
PLUS like roadlessgraveled mentioned, you get that added bonus of busting open your knuckles on the nearest sharp object when they round off your bolt.

Happy stripping :) ............
