We've done it numerous times, on 550s all the way up to CIMs, without any issue. It's plenty reliable if the fasteners are tight.

You shouldn't use a socket head by itself as it's small head diameter doesn't grab a lot of meat, so we use buttons or a washer in addition.

The primary reason reason for out drivetrain failing this year was tension-held bearing blocks on the corners of our WCD. There were two screws going through the bearing blocks on either side of the 2x1 with nuts on the other end. No matter how much we tightened the screws, the bearing blocks would always slip and cause drivetrain failure.After adding some sandpaper-like gripping tape in between the bearing blocks and the 2x1 post-season, we no longer had problems with the drivetrain failing. This is why I always recommend against any kind of friction fits.
Now, the forces are less extreme on the first stage of a transmission, but I still wouldn't do it in the middle of the season.
