Q: How do you install this plug?
Drill a 5/16" deep hole with a 5/8" Forstner bit, then set the plug in place with adhesive; the grooved shank locks in mechanically as the adhesive cures to create a keyhole slot ready for hanging.
05H0301 - Keyhole Slot Plug, each

This brass insert takes all the trouble out of making a keyhole slot for hanging pictures or other items - no routing required. The plug mounts in a 5/16" deep hole made with a 5/8" forstner bit (sold separately) and is secured with adhesive; the grooved shank provides a good mechanical glue lock.
Only a single plug is needed to hold a small frame, but additional plugs can be used to hold larger items or prevent rotation. The keyhole opening is sized to fit common #8 screws.

It's sized for common #8 screws, the size used on most picture-hanging hardware.
No, that's the point: the plug replaces the router setup a traditional keyhole slot requires, needing only a drilled hole and some adhesive.
A single plug holds a small frame on its own; adding more spreads the load for larger items or keeps them from rotating once hung.
