Vintage Spartan trailer shells and the shells of some other aircraft style trailers were made with 1/8" universal head (AN470) rivets. This 3" straight rivet set is the correct shape and size for bucking all 1/8" diameter universal head rivets.

Note: Airstream never used universal head rivets. We sell the brazier head set for Airstreams.

This set has a .401" shank.
