Drywall fastener for shelf support
First photo shows the 1/4 inch diameter fastener that I'm needing info about. The others are for context; I suspect the construction company bought this shelving as kits.
Is this just a nail with a very thick head? Can I remove it to reinstall the support over a wall stud? Will I damage my drywall by removing it (I can mud over a nail hole)?
If I can't "safely" remove it, would I be able to find similar support braces elsewhere to put on the stud locations?
