Q: How much weight can a floating shelf support?
With this hardware, a pair of supports on a 4"-deep shelf holds up to 100 lb, or up to 50 lb if the shelf is 8" deep; adding a third support increases capacity further.
00S0520 - Blind Shelf Supports, pair

Made of zinc-plated steel, a pair of these blind shelf supports will invisibly hold a 1" or thicker shelf. Each mounting plate is anchored to the wall studs with two flat-head screws, and the projecting 5" long hex posts slip into 7/16" holes drilled in the back side of the shelf. Even if your holes end up slightly undersize, the corners of the hex post will cut their way in.
The design ensures that the alloy steel coupling screws remain tensioned between the posts and inserts in the plates, yielding a respectable capacity of 100 lb for a 4" deep shelf and up to 50 lb at 8" deep*.
Additional supports are sold singly for increasing load capacity on shelves long enough to span more than two studs; each extra support adds 50 lb more capacity at 4" deep, and 25 lb more at 8" deep*.
The simple instructions included make installation a snap.
Made in Canada.
* These capacity ratings are based on evenly distributed loads. Keeping the load more toward the rear of the shelf will increase the capacity and decrease deflection.
Note: For shelves narrower than 5 1/4", you will have to cut some of the non-threaded end of the hex post (with a hacksaw), so the posts are roughly 3/8" shorter than the shelf's depth.

Drill a 7/16" hole into the underside of the shelf for each hex post, sized to grip the post snugly without splitting the wood.
Installing blind shelf supports starts with screwing the mounting plate to a wall stud, then pressing the shelf's drilled holes onto the projecting 5" hex posts so the shelf appears to float without visible brackets.
For shelves narrower than 5 1/4", cut about 3/8" off the hex post's end with a hacksaw so it doesn't project past the shelf's front edge.
They're zinc-coated steel, chosen to resist corrosion at the hidden mounting point inside the wall and shelf.
