I needed a “tool free” 3/8" diameter bolt and nut for an outdoor application. The thread pattern on this 1.25" (31mm) long bolt matches conventional 3/8" metal bolts. I also included a separate 1.5" diam cap to fit over the head of 3/8" hex head bolts and nuts to allow them to be used in tool-free mode.
I printed these parts from ASA, which provides good UV resistance, moisture resistance, and mechanical strength. Imagine a bolt and nut made from a material very similar to that used to make Lego's but with better UV resistance.
