Just the other week I was thinking: the hardware store is my bolt lengthener. I had a bolt that was too short, and no means to make it longer. I simply went to the hardware store and got a replacement. Of course this encumbers all of the requisite industries (mining, manufacturing, shipping, and a mom-and-pop shop correctly guessing what I would need and being willing to stock it). But for me, it all wraps up functionally into being a bolt lengthener.

Yes, all the time..... :)
