Tail Light cover screw

So I was trying to adjust the positioning of the tail lights on my 987.2 Cayman by loosening and re-tightening the 3 bolts on the screws holding the tail lights inside the trunk and accidentally broke one of the screw off by tightening it too much. Called the parts service to order the screw part after looking it up : 2009-2016 Porsche Cover Screw 997-631-497-00 | Sunset Porsche Parts 2009-2016 Porsche part # 997-631-497-00 - Cover Screw www.sunsetporscheparts.com But from the graphics on the site, the images doesn't seem to exactly match? How are the screw pieces taken off the tail lights and put on?

Looking at my copy of the PET, that part number looks like the screw that holds in the bulb, not the mounting stud you're looking for. See #4 in the pic below. I don't see the mounting stud listed as a separate part.

The stud you broke off is part of the taillight assembly and I don't think it's available separately. How you fix this depends on how you broke it. You'll probably need to use glue, though if you broke the plastic that can be challenging to glue. If you broke the metal you may be able to use JB Weld . Torque spec on those nuts is only 2 ft-lb, which isn't very much. That's probably why it broke.

I broke the metal piece. So no replacement part?

If you broke the metal and there's enough purchase left sticking out you could "collar it" and epoxy it with a split metal sleeve. Otherwise you're better off just buying a new one and considering it "credit hours" in repair school. PS If that's a power driver in your right hand, the one labeled "Fuel" switch to a ratchet for delicate applications.

It's broke at the base, I'll try 2 part epoxy glue first before buying a completely new assembly..

Trying first is is definitely the right call, success is going to depend on how much surface area you have. I sincerely doubt a shaft to shaft epoxy job would do it but no harm in the endeavor, if you can catch some base around it without compromising the assembly it might work, good luck!

I could tell the JB weld wasn't going to really be foolproof and spotty at best due to the small size of the screw. Since there was only a slight wiggle with the top screw missing, I've just used zip tie to hold the top portion in place and it seems to have done the trick. Lesson learned don't over torque screws.

You'd be surprised at how well JB works metal-to-metal, and that screw doesn't need to hold a lot of torque. But it sounds like you've found another solution that'll work fine.

Yeah thanks to everyone for their quick pointers and info. Seems zip tie is satisfactory without having to take apart the entire assembly and curing it over a day but I'll hold on to the broken piece just in case.

lain09 I found a broken stud on my 987.2 when I disassembled taillight for tinting and it took some digging to confirm I had the right part. Auto Atlanta was a big help.. I can confirm that item #5 in the scematic that Racergreg posted here is the stud. It is called an actuator in the list but when you select the part it says Stud. Stud. - Genuine Porsche G98763105300 Known as: actuator $4.75 ​

Nice! So is the silver screw that the red arrows are pointing to actually #5 in the parts diagram? I’m assuming then one side screws onto the taillight and one protrudes to place the bolt on to.

Correct, Threaded on both sides of the washer in the center. The hex head on the stud corresponds to a star socket to screw it into the tail light. As said previously... Not a lot of force when installing.

You made my day. Glad that I didn't plaster JB weld all over the it now! Going to put in an order at the dealership. I wonder if I still have to buy the screws I requested.
