One screw (CMZ0408) holds the axle to the hub. Two longer screws
(CMZ0414) hold the drum to the hub. There is normally a hole in the
brake drum that you can tighten the screw holding the axle. The splined
adapter is just held on by the five axle studs/nuts.
The screws are 1/4" long and 7/8" long, overall length.
