You check the diameter of hole required, then choose a drill bit one millimeter
narrower. You’re tried drilling the specified hole size many times in the past, only for
it to be too big, leaving the __screwdriver__ spinning in the hole when you try to
tighten the __screw___. You decide it’s better to ensure a tight fit. So you drill
a smaller hole than suggested, then attempt to hammer in the plug. It bends
sideways, useless. You try again. And again. Eventually, you manage to get a plug
into the hole. You insert the end of the screw, pick up your _head__ and get
to work. It certainly is a tight fit and hard work. And as the screw goes in, the plug
starts to __set in__. By the time the screw’s halfway in, the screwdriver
has slopped off the screw so many times that what used to be a _Crosshead_
pattern on the screw ____plug_. Now looks more like a smooth, round hole.
It’s impossible to screw it in any further or unscrew it. So you take a pair of pliers,
grip the end of the screw, and attempt to drag the whole thing out of the wall. But
the _pullout_ force is beyond the power of your now-aching arms. The screw
might as well be ___expand .with epoxy resin.
