Or

What does the build manual say? Whatever that says, do it. Are you talking about the bolts that hold the blades into the grips or the feathering shaft bolts that hold the grips onto the feathering shaft?

For installing the blades into the grips?

Shouldn't have to use any spacers. What blades?

Try tightening them up but it shouldn't take much force, you want the blades quite tight in the grips.
