Abstract: A tooth adapter defining top and bottom walls and side walls, an adapter recess in one side, a retention means in the adapter recess, a bolt with a fastening inserted in the recess, a collar formed on the bolt of predetermined diameter, a tooth having side walls and defining a hollow chamber fitting over the adaptor, a through tooth bolt opening formed in a tooth side wall of predetermined diameter, the tooth bolt opening being located to register with the adaptor recess, when the tooth is positioned on the adapter. In one version the diameter of the collar is slightly greater than the diameter of the tooth bolt opening, to create a locking effect.
