Tusker Brass Thumscrew

This is the small brass thumbscrew that locks the stem connector (part 201) and the short brass stem (part 202) together on your Tusker energy free or electric waterer valve. It threads in by hand, no tools required, and holds the float arm firmly to the valve so it will not slip, spin loose, or drop out of adjustment while your animals are drinking.

It is a tiny part, but if it strips out, snaps, or goes missing, the whole float arm connection can work its way loose and throw off your water level. Keeping a spare on hand means a five minute fix instead of a call for help.
