Product review (2 stars): PAY ATTENTION!! Dimensions are all wrong.
Product dimension states - 1.5 x 2.5 x 3.5 inches  - These are NOT 3.5" in any direction. They are 1-27/32" tall. 13/16" thread. 1-3/8" foot-width. 8 threads.  The dimensions stated and the picture is much taller than the foot I received, this time.  I ordered one of these in October and it was 3-1/2" tall and is exactly what I wanted.  These will go back.
