It doesn't take much heat..........just need to direct it to the head of the screw to lengthen the screw ever so slightly and release the fastener. If you can get the screw up to 200F., it will release.

This is what happened, working first on the driver's side...

The torch worked on one of screws. The other 3 got stripped.

I noticed the heat started melting the plastic - it was broken for the most part. This broken ramp made it hard to close the door properly, which is why I decided to change all the catches on each door.

So I took all the broken plastic (ramp) out, thinking I can possibly replace just the ramp from the new component.

(And I'm thinking, before I go any further, I need to go to Napa's and get the same sized screws to replace the ones that are stripped. And probably pick up that Craftsman "Screw-out Damaged Screw Remover Set" I saw at the store yesterday.)

But now the door closes perfectly. What is the point of changing the catch now?

At least I will have more time now to change these catches - am thinking about ordering a Snap on extractor set, maybe that would work on the stripped screws.

I got a couple of those stripped hex's out with a screw extractor. Wasn't fun, but the bit eventually took them out.

Gonna take the stripped screws out and change the catch, but it looks like it will be eventually, as I need to get a screw extractor and the replacement bolts first.

Most of the design aspects that Mercedes produces, at least the ones related to the 240D, are very good, IMO. But this hex bolt design that gets easily stripped is not one of the better ones. But then again, once I picked out the broken plastic, the catch works just like new.

Question for those who had stripped hex's:

Napa did not have these.

Where did you find the replacement bolts?

Did you find them at a store, online or ??? I don't want to take the old ones out until I find the new ones.

Mine were the panhead phillips and they had to come from the dealer.

If they are standard socket head cap screws, any decent hardware store will have them........but, they'll probably be black.

Otherwise..........it's the dealer.

Ok, to the dealer it is...thought I might have to try there, but I usually go there as a last resort, if you know what I mean

But I might try Lowes later this afternoon, just for the heck of it, since I'm going there for other things...but it will probably be an order through the dealer.

Thanks for the reply, Brian.

These fasteners are a safety item, ask any automotive impact testing engineer.


SCREW, for mounting door lock CATCH to body.

Personally I prefer drilling the head off, and removing the stub with vice grips.






Have a great day.
