Our 3/8" diameter Jumbo Head Drive Rivet is designed specifically for the traffic sign application.  Quickly mount a sign to a square post with just a hammer. The flush type head makes it difficult for vandals to remove. The 1" Head Diameter has 40% more contact than competetive drive rivets for increased wind load. Each Jumbo Head Drive Rivet comes with a Nylon Washer which helps protect the reflective sheeting when mounting signs.

 

If you're having a problem with your drive rivets, it could be that you're using an aluminum drive rivet.
