dmikee,
The counterweights, as mounted on your K-27 each have a small plastic "filler" inserted in each counterweight. That "filler" has a small hole so that a Phillips head screw driver can be inserted to remove the screw that secures the counterweight.
With the six replacements you received what you are looking at is the counterweights without those plastic fillers inserted. There should be six new "filler" caps packed with the replacement counterweights. Once the counterweights are replaced, then these fillers are pushed into the counterweight.

This is a link to a detailed article on counterweight replacement. It has pictures of the procedure along with the tools listed, just two, required to replace the counterweights.

The Bach Man, early on posted the procedure to replace the counterweights. Above is the link.
Total time to replace six counterweights may be all of twenty or so minutes.
