Oval floor mat retaining screws for MKIV.
ONLY FOR MATS WITH OVAL RETAINING HOLES. VW used both round retainers that were pin-and-click type as well as oval retainers that rotates to lock in place. These are only for the oval turn and lock style.
Oval retainers were used on late model 02-03 Carpet mats. Round retainers are used on all rubber mats and early model carpet mats.
