The installer was holding the bracket in position and held a tek screw up to the bracket to
fix it. The direction of the tek gun was in the forward position as he pressed the trigger
and the tek screw started to turn into the masonry. Then it started to tighten more than he
felt it should, and wasn't right, so he reversed the drill to draw the screw back out again.
As the screw was reversed enough to release the bracket from the wall, the installer took
the bracket away from the wall and held it in his hand, but the screw was still halfway
through the fixing hole in the bracket.

He was distracted by someone who sounded their horn, so he turned around to look at
what was happening. It was an automatic reflex to change the direction of the drill to
forward before drilling again and as he was holding the bracket steady in his hand, he put
the drill bit over the tek screw and pulled the trigger. The screw moved forward again,
rather than continuing to pull out, the screw was forced forward, further through the fixing
hole, through his glove and into his hand. As a result then found himself with a tek screw
through one side of the flesh part between his index finger and thumb on his left hand,
attaching the bracket to the inside of this hand.
