Team 104 has used 1/4" steel rivets with back up washers since 2001 except the stack attack when we tried a 8020 frame. We have never had a riveted joint fail. For 2006 we bolted the kit chaise together and when the design became fixed backed up the bolts with rivets. We built up the kit frame with 1" 6061-t6 angle. The frame worked just fine.
