In my year's of ownership of Asian-manufactured automobiles, as well as
other products built in the same area, this is normal manufacturing
procedure. It is a QC check on the proper installation (and, torque if
applicable) of each fastener. My very first Honda back in the '70s had
them as well. I've noted the same thing on the 2006 Elantra I bought
last month.
