None of them can be detached for wall mounting. I've used hundreds of these in my life and this is by far the worst.

The screw loosened the threads before the center gave way and secured the anchor. Worst Molly Bolt I've ever eaten. Return to Home Depot. Throw away money to save a few bucks and order delivery. :(
