nope, no bolts at all... The steel ring fits real snug over the surround, and tight to the basket, then there is an aluminum band that snaps on, and hold the ring tight to the basket. It's really a pretty cool design. Someone was REALLY thinking outside the box to come up with this design!!! I haven't looked close enough, but if the spider is mechanicly held in place too, and not glued, you could re-cone one of these in 1 minute yourself.
