Mixed sizes
Expected uniform sizing but there was slight variation in the pack. Still usable though.

Good product
Works well but sharp edges require care during installation. Overall good value for the price.

Very secure locking mechanism. Used these on my motorcycle engine and they haven't loosened at all.
