ABSTRACT:
The phenomenon of pop-back of the nail insert for anchor nail fasteners is prevented by providing a dimple-like indentation in the wall of the tube sufficient to grip the insert nail after it has been driven down the tube. For longer length anchor nails, two such dimple-like indentations may be provided.
