The case of a stepper motor 5mm shaft connecting to a 8mm positioning lead screw. 5 assemblies in this set, each assembly has 4 lock screws, Allen wrench, and coupler tube. The lead screw common diameter/size of 8mm that matches one end of this coupler tube. The stepper motors often have a 3mm output shaft that is the hole size of the opposite end of this coupler tube. The small CNC kit commonly would use the coupler kit like this per axis.
