Square Pegboard Hook with Lock

In my case all the square pegboards I measured were sized at 10mm H and 9.7mm W.

So I remixed Svettis design to fit more snugly in the boards I want to use in. I resized the hook attachment to be 9.5mmX9.5mm and while I was doing so I thought of adding locks so it sticks in it location without movements.

The design it self has no issues and its unchanged, its strong and can handle weights easily.
