We believe it provides a better seal over time, and the rivet sits tightly against the skin for a more original look. When using Olympic rivets on the exterior of an Airstream, Spartan or any other travel trailer, we recommend using the type WITHOUT washers in almost all applications. When done correctly, the mandrel and very top of the head are shaved to form a solid dome. To correctly finish the rivet, the mandrel (which breaks above the head of the rivet), must be snipped flush with the rivet head and then shaved with a specially sized shaver tool. The bulb-tite is a blind "pop" rivet that when installed-and shaved correctly-closely resembles a true solid head rivet. It is the only rivet on the market that looks like a solid dome head rivet when finished. Gesipa Fasteners developed the Olympic Bulb-Tite rivet for exactly this situation. To make repairs and replace those rivets while the interior walls are in place, the best solution is a solid head look-alike. To install solid head rivets, you need to have access to the front and back of the rivet.Īfter the interior walls have been installed, you can no longer get to the back of the rivets used on the shell. This sequence allows the factory to use solid head "buck" aircraft rivets in attaching the shell to the aluminum ribs. When a riveted trailer is assembled at the factory, the inside walls are not attached until after the exterior shell is constructed.
