How do hollow bolts work?

A typical connection is made by inserting the hollow bolt into the pre-drilled holes of the fixture and hollow section. As the
bolt head is tightened, the cone is pulled up the bolt thread, causing the sleeve to expand until the cone locks the sleeve
against the hollow section's inner wall.
