Alright so I had the same failure happen on my Kenmore oven. The part is obviously poorly designed and is a hodge podge of Chinese and American standards.

Solution: Remove the handle from the oven. Remove bushings from the handle (Do not strip handle threads!!!). Go buy an M8 (1.25)-40mm machine screw and collar washer from big box store. It'll screw right into place and oddly fits the holes in the oven perfectly. You may have to widen the plastic holes. I used a 19/64 bit
