If you measured correctly and ordered correctly and double checked it there is nothing to write about other than “it fits”

Worked for my purpose. I could not find anything metric in my local hardware stores. I had heat trace electrical boxes that came with slotted screws, so a screwdriver was needed whenever we needed to change parameters. So....People were just leaving many of the boxes open. By installing these, we are now able to use our fingers to get in and out of the boxes so it keeps dirt out. Working great so far.
