Theo86 Posted April 19, 2020 Report Share Posted April 19, 2020 Yesterday evening I snapped off two of the sill studs on the rear undertray trying to remove the 10mm plastic nuts. What is a good solution for replacement? Link to comment Share on other sites More sharing options...

Neat. 👍 Link to comment Share on other sites More sharing options...
pipsqueak Posted April 21, 2020 Report Share Posted April 21, 2020 You could try bonded studs https://shop4fasteners.co.uk/fasteners/bonding-fasteners/male-stud-bonding-fasteners.html Link to comment Share on other sites More sharing options...

Neat. 👍 Thank you all...looked at a video on nutserts today. Seems it might be a good option. Need to see the best package to buy. Anyway you can recommend best option. This is really only for the snapped off studs... Link to comment Share on other sites More sharing options...
JohnnyUK Posted April 22, 2020 Report Share Posted April 22, 2020 All over engineered as usual... There is no load on the panel. (Apart from airflow if it's not tucked in!) Link to comment Share on other sites More sharing options...
Theo86 Posted April 23, 2020 Author Report Share Posted April 23, 2020 I don't think the rear tray has ever been off the car. 20 years old car...these studs rust up pretty bad and almost cement onto the plastic nut. IMO stainless steel would have been better. My friend with an old Audi RS4 has the same issue. Link to comment Share on other sites More sharing options...
