That shelf was rock solid on the wall with zero play

I hung up a shelf on drywall

Used to hang floating shelf, about 35 lbs with books - 1 screw directly to stud, 2 drywall screws, feels sturdy.

These are not shelf drilling they break when u try an if you do drill a whole make sure its big enough or they break i dont recommend such a misleading prodict

Used them today to hang a 4ft shelf.

These worked well for the shelf and picture hanging projects I just finished.

The shelf fell off the same day
