Product review (4 stars): Specialty Screw and Nut for Dryer
It was the correct one for my Whirlpool Duet Dryer. No stores in my area carried this hardware and some places online wanted $30 or more for the set of 3. I ordered only one because I mistakenly thought it was a set of three, not a sigle screw with nut, so look out if you need more than one.
