set screw

A home owner from West Palm Beach,FL says:
Does this unit use a set screw? I am looking for a crank in white, approx 7/16 diameter hole (spline?)that does NOT use a set screw. I know some of these just snap on, eliminating the old problem of set screw-caused damage.

Yes, the 39-227B uses a set screw. If you have a Pella window we do not have a snap on handle version.
