the Sonos Era100 floor stands

Recently purchased a set of ERA100 floor stands but had a real issue with the build. The kit comes with four M5 long screws that were too long to fit securely through the base and into the poles. My build issues continued when one screw got stuck and I had to drill it out and retap the pole with an m6 thread. I cut about a quarter inch of the other 3 long bolts and that did the trick. Good secure fixture top and bottom. The issue as I see it is either the build needs shorter M5 screws or longer threaded receptacles in the poles. My advice would be make sure the long screws go all the way into the poles before you start the build.
