2nd year apprentice had the task.

I had already drilled the holes and fitted the red rawl plugs. About a 2m length of
dado.

He has access to a screw box and an impact driver (with a proper PZ2 bit fitted).

So how long?

3 h



How many screws did he break by using the impact driver in
full-on gorilla mode ?.

In full gorilla mode he would have driven the screw head completely through what he was
trying to fix, necessitating a screw with a larger head or a big washer.

That's after he's managed to remove that screw complete with
plug possibly bringing bits of plasterboard and brick dust with it thus
requiring the drilling of an even bigger hole, maybe requiring a brown plug
and a fatter screw this time.


Probably the closest.

The actual answer is that he was unable to to the job.

He used 3" screws, rammed them in all the way thus pulling out the red
plug. He managed on every red plug.

Absolutely useless.
