All,
I am sure this has been discussed before, but I'll be darned if I can find it...

While at SNF next week I want to purchase some extra blind rivets to have on hand just in case... I want to get some LP4-3's, LP4-4's (for leading edge ribs to main spar), and CS4-4's. However, it appears that only Van's uses these part numbers. Does anyone know what the equivalent part numbers would be from other suppliers?

Thanks,

Aircraft Spruce carries Cherry commercial rivets.

BSP-43 will sub for LP4-3
BSP-44 will sub for LP4-4
BSC-44 will sub for CS4-4

Avex

At least some of those rivets - like the CS4-x you mention are Avex rivets like the ones used by Chris Heintz in his designs. They compress in stages to look like the Michelin man and retain the mandrel. Also and importantly, they are better at filling the hole than a regular blind rivet. Test them and you will see this. This is no criticism of Cherry, I'm just adding data.
