When I bought 4x8 sheets of white pegboard from Home Depot, the webpage said the holes were 9/32". They are actually .236in, or about 6mm. Which means that none of the hooks meant for 1/4" holes would fit.

But, maybe luckily so, as now I have much more solid and better looking hooks. I have included the Fusion 360 file so you can make any changes you like.

• The "hook" part of it is a section of 5mm birch dowel, any length you like. They are pretty snug as friction fit by twisting them in, or you can glue them for extra strength if you like. The dowel should be pushed through, extending 3/16" or more so that it can fit in the hole below the plastic rivet. This prevents the hook from rotating.

• A plastic rivet is used to secure the hook to the pegboard. But the plastic "screws" that come with the rivets do not unscrew, so you can't easily remove the hooks if you use these. So I use #8 x 3/4" panhead screws (black) instead, and now the hooks are easily removeable if you need to relocate them.

• These are mostly decorative, covering the end grain of the dowels. They come in lots of colors.
