Notice also, that there is a screwdriver slot at each end. This is so the item can be removed and inserted backwards to utilize the opposite magnetic pole if and when needed.

Good luck if you try to manufacture them. Donor sets are a protentional source; I had been fortunate to have located some that way.

I wonder if they were making it by magnetizing a threaded rod or by adding threads to a cylindrical bar magnet? It is hard to make a nail into a strong magnet, but most strong magnets that I've split the pieces all seemed to stay strong...
