Product review (3 stars): You only get one stud- not four.
These shelf studs are common to many refrigerators similar to my Kitchenaid superba and over the years I have replaced several as they merely lock into the side wall of the appliance and thus depend on the side wall for support.  This means that they eventually break due to the pressure placed on the shelves they support.  My local supply house did not have the studs in stock so I ordered via Amazon.  My mistake, and yes it was my mistake, was that I did not read the description carefully because I believed I was getting 4 studs but he package provided only one.  The write up states:"THIS WHIRLPOOL 1115290 SHELF SUPPORT STUD (1 OF 4) IS DESIGNED TO WORK WITH MANY WHIRLPOOL."  I read the statement that the item I was ordering consisted of 4 studs because I was in too much of a hurry to carefully parse the prose.  Re-read it clears states "This...stud..."  and as my mother would say - well that's for another review.  The purpose of this review is to make two points:
1.  The stud is the same as the OEM part and
2.  You only get one for the advertised price.
