Jennifer E Kimberling City , MO October 05, 2020 My old mixer bowl would come off the stand even though it was in the locked position. I bought a new mixer bowl and cap screw in hopes that one of these would fix the problem. Our old mixer bowl works with the new cap screw and the new bowl has an even tighter fit.
