Wood – Mystery connector search

connectorsshelvingwoodworking

To fix a bookcase built by my dad who died last year, I am looking for the nylon or plastic connector that he used. They consist of a threaded dowel 3” by1/2” and threaded inserts 1”-wide insert for the 1/2”-threaded nut. They works really well making bookshelves with the inserts in the shelf boards and in the spindles. However, I have been unable to find anywhere.

Any suggestions?

I would call those fluted dowel pins. I use a similar style of pre made dowels. Finding that exact model may take some time but give fluted dowel pins or rods and that should get you close.
