I have a Kenmore gas stove top.  Current Kenmore shaft is around 0.196" diameter and 0.216" length.  This product is around 0.196" diameter BUT 0.275" longer.  Just cut the tip off as the RTV is what really holds it into place.  Note: When using the RTV, squeeze a little onto a towel first as it was clear then black.
