20x Nuts for Saab Plastic Unthreaded 4mm Diameter Hole Bumpers Wheel Arch Lining

 

These are used on YS3G/F for attaching wheel arch linings, splash guards and some bumper parts and trims. Once removed they are damaged and don't hold as tight so it is best to replace them to avoid losing them while on the road.

 

The hole diameter is 4mm and the collar diameter is 16mm
