Trying to take bumper off (thread gone on one screw)

[Whosane]

Sorry to report,

but unfortunately I managed to f*** up one of the T20 screws in the wheel arch to take the bumper off. It's now well and truly gone. I can still tighten the screw for some reason, but can't loosen it. Applied many theories such as gentle whilst pushing down, but it doesn't work. Is there any way I can take the T20 screw out?

Also, does anyone have a link to some new T20 screws. I may as well replace all of them in the bumper, so that's 4 in total?

Use a dremel and cut the top off it the rest will drop out then

It's screwed in fully. It can be tightened slightly more but I left it, so that's not possible.

Remove the under tray (if fitted and look up towards where the screw is. You should see a little plastic nut (orange in colour). These normally clip onto the bumper and have a lip on them to hold them in place while tightening and loosening them.

Us a pair of pliers to hold the nut while you screw the screw out. Either that or use a grinder to buff the head off of the screw. Then just replace the screw and orange nut
