I know this is not exactly exciting stuff, but I need help IDing a rivet for a boot. One of the straps on my Starship Troopers boot has come off and it was held on by some sort of rivet. Below is a picture of the head of the rivet as well as an inset picture with the bottom and shaft. The bottom disc is abpprox 3/8" across and the shaft, slightly compacted, is 1/4" high. The black coated head piece is also approx 3/8" across. Does anyone know exactly what these are called and where I might get some? Thanks for your time.
