It is the original screw from my Power-fin agitator...thought I lost it...had been misplaced...finally found it.
I suppose the hole was stripped in my Power-fin but, it's the same lock screw needed for the PowerFlex 12 agitator.
Lorainfurniture (great guy), donated a screw but, it was too small.
My PowerFlex 12 agitator screw hole had to be made so, I don't believe the threads are stripped...agitator cannot be stripped because it's fairly new.
I'm going to clean the screw and see if it makes a difference.
Hopefully, I don't have to buy a larger replacement screw.
