Strong Floating Shelves The Strongest Option

First video on Strong Floating Shelves:

After experimenting with floating shelves for several years now, I've found ways to make them strong using lag bolts and wooden dowels. But the strongest option yet that I explore in this video uses 5/8 inch steel all thread rods as shelf supports for floating shelves. Wood works fine, but it doesn't really compare to the strength that you get with steel rods.
