Just for info, NEVER REPLACE THIS SCREW WITH A LONGER ONE!!!!!! I thought this screw was to hold the side gasket in and it didn't seem like it was doing its job so I installed a longer screw, which went into the motor, which, of course, cut one of the connecting wires disabling the motor. Many $$$$$ to replace the motor. Luckily where my son works there's this genius electrical guy who took it apart and reinstalled the wire. Works like new.
