To keep from chasing/losing the side panel bolts I put faucet washers on the bolts to keep them from falling out of the panel. No need to tap it,just hold the washer with pliers and screw the bolt into it. Stop turning the bolt when the washer is at the surface of the plastic. The friction on the threads holds the washer to the bolt. The washer stays with the bolt and spins as the bolt is removed. I haven't had to chase a bolt since I put the washers on.
