Product review (2 stars): Check the depth of your stem.
The two adaptors are only 1/8th and 1/4 " deep. if the stem the knob fits onto is further away from the surface face of your oven, these will not fit. My oven stems are 1/4" beneath the surface face of my oven and I cannot use them. I tried using super glue to put two together and salvage this purchase, but the glue did not hold.
