If it's not too late, let me suggest brazing
the parts together. The zinc coatings make a great flux for the molten bronze to sweat into the joints. It would only take a little brazing to make disassembly impossible. The original zinc will stay in place to protect the steel and the bronze also will not rust. To weld the parts, the zinc will have to be ground away and the bead and ground portions will rust.
Anyone else wishing to secure parts together on your courses: this brazing process can be easily done in place with a portable oxy/acetylene outfit. No need to pull baskets to do it.
Insurance for baskets? Figure the cost of replaced baskets plus profits for the greed industry. The mob would love for us to be paying for its protection. They'd probably steal them just to build the market.
