A light-hearted jest prompts the serious question: how does your team handle multiple thread pitches of the same diameter screws and nuts?
On one mechanism of our 2020 robot in particular, #10-24 and #10-32 hardware ended up being used interchangeably. This proved a real issue, especially when we disassembled things to make changes. Many a brave little locknut lost its life to the evil cross-threading monster. Yes, it’s possible to tell them apart, but in the heat of build season and with screws strewn about, the tendency is to just try the fit.
Is the easiest solution to keep only one in stock? In that case do we opt for finer or coarser threads? What about specifying carefully in drawings? Stocking them in distinguishable finishes?
