I love making, fixing and modifying things. This means that you should always have different types of gear on hand. This little box has made my life so much easier. For some reason I have a pathetic set of bolts, washers and lock washers, except for the M8 used in the car. So the last time I wanted to build something, I had exactly what I needed. Relax! Part of me wishes everything was metric, it made more sense to me, but with this range and price I'm not going to complain.
