'F' shows recommended orientation of flatted shaft in set screw hub.
ØD
Note that both traction and concentricity may be affected when
using an adaptor. For best results shafts with h6 tolerance or
better, are recommended. Undersized shafts become
progressively less effective. For similar reasons, flatted shafts with
more than 1/4 of their diameter removed are not recommended.
