Well this is a turn around from when first I asked that same question a few years ago after our first FTC season demonstrated how horrible the TETRIX axles are. We ended up belt sanding flats on 3/16" solid round hardened stainless steel shafts -- very tedious but totally worth it.

Unfortunately, the McMaster link does not go down to the 3/16" diameter needed to match up with thr TETRIX hubs and bearings, etc. - but other sources do have the needed 3/16" size D-shaft. The 10-32 Grade8 SH Cap Screws do require a a very slight reaming of the TETRIX hubs to fit them, but this only improves the precision of the fit.

Good news & thanks for the update.
