Win the battle of bulging bins
I have a lot of fasteners and other hardware stashed in low-cost plastic bins. They work fine, until you stack them three or four high, when they tend to collapse on each other, as the lower-bin sides begin to bulge out from the weight of upper bins.
To prevent that, empty a bin, drill two holes opposite each other, where shown, and insert a plastic cable tie (also known as a zip tie). Then, snip the female end off another tie (Tie 2 in the drawing) and fit it onto Tie 1. Tighten up Tie 2 just enough to keep the bin wall from bulging outward. Snip off the excess material on Tie 1.
