The German helmet rivets (Splinte) or split pins History, Facts and Dates
The purpose of the three rivets (split pins or Splinte in German) is to secure the liner to the shell. One is located at the back and two at the front. The rivets were inserted through the three holes in the helmet shell and the outer band of the liner. A flat washer with two rectangular holes was installed before bending the two parts flat to opposite directions.
The early rivets were made of brass and then zinczoated (not all the time, you can find a lot uncoated early pins). This was done to prevent corrosion. They where made out of four parts: A firm base, the head, the prongs and the washer. Brass rivets were not strong enough and its production was stopped. Later pens are made of steel.
The manufacturers had to place a maker stamp on one of the legs of a split pin. In the early years they didn’t. From 1938 most rivets have a maker mark.
