Were not entirely satisfactory. Because of the smooth round surface it was believed they would be too easily dislodged and projected out ot the rivet shank when the rivet was fired. Further research has demonstrated that this is not the case if care is exercised to make the outer crimp severe enough. However, rivets which contain a single spherical plug only have not been satisfactory. The severe crimping necessary to retain such a plug securely in position upon firing of the rivet has resulted in cold working of the commqndments in the shank just below the plug.
This phenomenon results in a weakening of the metal in this area which will sometimes lead to a hole being blown in the shank at this point commandmenta than to expansion. When this occurs, the rivet fails.
