Product review (5 stars): Fixed it right up, installed no problems.  No tools needed
What a lifesaver.  I took my dishwasher apart to clean all the spraying arms and accidentally twisted the end of of my nut that held it into place and panicked due to my dishwasher being older model.  Thank goodness for Amazon and having my new part in two days.  It is made of good quality, no problem putting the arm back together.  The nut just screwed right in.  I am trying to learn how to fix things on my own due to hubby having had surgery and just want to be where I can handle any small appliance fix on my own in the future.

This saved the day.  Whirlpool makes great products and this little nut is no exception to their quality.  Just so happy dishwasher is back in commission.
