Just some details from the Insert Tool packaging on how it works and how to use it.

Well, the bad news is I broke the Surebonder tool. While my ability to break the tool handle stokes my fragile male ego, ultimately, I concede that this is an indication of poor manufacturing as I am sure I am not the hand wrestling champion in my weight class.

The good news is that I was able to replace the two original brass parts on the roof latch with the threaded inserts. I went for a test drive with the top up and magically, most of my "dash" and wind noises have been greatly reduced. I am really quite amazed at how much one screw made a difference. I don't know if this fixes my intermittent problem with my top operation but I'll just have to wait and see.

Some things I learned while doing this:

1. Cover the interior of your car with a tarp. Brass filings will be everywhere to mar your finish and possibly cause electrical problems in an already flaky grounded Boxster. Have your Shop Vac handy.

2. The broken brass nut was a pain to remove. It had broken into three large pieces which wouldn't fit through the hole. I was able to remove them by wedging the hole so a piece wouldn't move and using a small drill bit in a thin area to break the piece into smaller pieces.

3. The screw I used is 1/4 x 20 x 1, black finish, flat head, socket cap, allen instead of torx. It's not the original metric part but it's pretty close. I guess technically my Boxster is now a renegade hybrid since I used english measure parts.

4. It's not a bad idea to do the preventative maintenance by removing the good brass captive nuts. I had an easier time with the good one because the drill didn't walk. The trick I used was to use progressively larger drill bits. I started with a 1/4" bit, 3/8" and lastly the recommended 25/64". I used needle nose pliers to clean up as best as possible.

5. Use masking tape to mark depth as MNBoxster (Jim) recommends.

6. Wear safety glasses.

7. I used my 18V battery powered drill.

I will return my broken Surebonder tool tomorrow and get a replacement. I might pick up an extra since my experience to date shows that the tool is only good for two inserts.

I broke the second Surebonder tool so I can't recommend it. It failed the same way - the handle broke at where it meets the mandrel. So next when I have time, I will try out the Marson 39200 Threadsert tool. Below are some examples of nutserts/rivet nuts available from Grainger.

Here is the Marson tool available from Grainger (4/6/2006 -I've since learned that the 1/4-20 mandrel does not come with 39200 model, contrary to the catalog description. I ordered one online from a company called Brady Tools)

Hi,

Good Job! See, it wasn't impossible at all!

Too bad about the first Tool. I bought the Marson Tool and it worked just fine for all 6 Rivnuts (I replaced them all while I was In There.

Sorry I didn't think to mention laying a Tarp to catch the Brass shavings, I remember vacuuming them up for months - good tip though.

Sounds like you had some trouble with the shattered Brass Nut, mine broke in convenient pieces, but you worked it all out!

I'm glad you took the time to post the pics and share your experience. It is such a poorly designed fastening system (using a Soft-Metal captive Nut to hold a highly tensioned Steel Screw - it's bound to fail with time), that for Porsche, it surprises me.

I'm sure that other Boxster Owners will encounter the same failure and maybe your experience will encourage some to perform the correction themselves. IMSM, the Dealer wanted $225 to perform the fix using the exact same technique and equipment - they turn that Marson Tool into a Profit Center! This is not something you need to pay a Dealer for!...

Happy Motoring!... Jim'99

Thanks for the compliment, Jim, but it wouldn't have been possible without your post. Of course, I'm going to distort the facts now and tell everyone that the Lotus Esprit mechanics/drivers and the jet fighter crowd really likes my work.

I had never have heard as such a fastener/tool before stumbling upon your post. I thought it important to give as much information since I found by personal experience, you can't go into the big box home improvement stores (Home Depot, Lowes) and find the tool and fasteners. Also, for less accomplished mechanics as myself, you can't get enough details before embarking on an anxiety-filled DIY (Zen and the Art of Boxster Maintenance.)

I, too, am disappointed on the use of steel screw and brass nuts at such a crucial location. Again, I am amazed at the difference one screw at the roof latch makes.

With this project I also learned something about the past of my Boxster. When I removed the roof latch there was an empty screw hole but no screw. I thought perhaps it had fallen out at one point, knocking the IR lens and dropped to the floorboard. Wait, what's with the abundance of wire nuts and 18 gauge wire doing up in here in the roof latch? Hmm, suction cups marks on the windshield when I bought the car. Maybe, somebody powered the radar detector from the roof latch area, splicing with household electrical wiring parts. I wonder ...

I'm not obsessing about this subject. I was actually looking for a car jack when I saw this tool. Note it does mention that's for aluminum.
