"Hartzell manual for the F flange section 3 of the prop manual s= ays 70-80 ft-lbs."
Secti= on 2 shows part number designation for all the props.  F flange is a C= ontinental design.  The HC-F2YR-1F is an R flange wit= h 60-70 ftlb specified.  When mounting a spinner backplate, = one really needs to be careful.  Only 20-22 ftlb on those.
