Default A Quick Question
I need to plug up 4 holes that have been drilled and dimpled for #8 screws. Question: what size flush head (AN426?) rivets should I use as plugs?
Thanks in advance,
Robin Hou

AN426 5-X (x depends on material thickness). Will still need some filler as this won't totally fill the dimple.

Default #8 Screw
A #8 screw is 0.164 OD. An AN426-5 rivet is 0.156 OD and an AN426-6 rivet is 0.187. The -5 is probably best. If you are just filling holes try to get an AN426A5 rivet, the A material is 1100 aluminum and will be easier to drive, but with reduced strength compared to an AN426AD5.

If you are just plugging holes in thin sheets with no structure behind it, be careful not to deform the sheet. Try practicing on some scrap before plugging the actual holes.

You can fill the holes with Hi LOck fasteners.
