They are slightly smaller in depth approx 3mm but that has no factor on their holding capacity

These are a direct replacement for the fender liner grommets on a gen1 2002 tundra

Just what i needed replace the old worn out grommets holds inner panel in very snuggly these grommets allowed me to fix a fender guard that was falling off on my 2000 tundra easily

Exact same diameter as the originals i pulled out and subsequently destroyed in doing so
