Could well be if no anti seize on the threads. Anyone know why they changed to 160nm.? ...120nm is plenty. Link to comment Share on other sites More sharing options...

The torque spec relies on the friction of the threads, you could end up stretching the bolts at 160nm with any grease on. I would not go higher than 120nm if putting anything on the threads.

I don't think Porsche say lube the threads anymore ? Maybe that's why they upped the torque.? Link to comment Share on other sites More sharing options...

tony_zx9r Posted December 15, 2019 Author Report Share Posted December 15, 2019 Just to finish this thread off, I got the Mcgard locking wheel bolts after waiting about 3 weeks. The correct versions for the 981 in black were so hard to get hold of. I fitted them today. The new Mcgard versions seem so much better than my OEM versions. I have a theory that because my tool has such thin shoulders that bend, they are just too delicate. I wonder if the unique design of each tool / bolt means that some owners will not have the really thin internals meaning some are possibly more reliable than others. I had problems getting the old ones off, had to tap the tool onto two of the old bolts and then struggled to get the bolt out of the tool. You will see from the pics below that the new Mcgard have much thicker internals and hopefully will last. Two old oem tools, both damaged new mcgard bolts & tool New vs old New bolt & tool If you ever have the same issue as myself with oem bolts/tool, I would suggest the Mcgard bolts are worth a look. For the 981 with oem alloys, the part no. is 28177 SUB Link to comment Share on other sites More sharing options...
T911UK Posted December 15, 2019 Report Share Posted December 15, 2019 The trouble with those is as they are thinner than OEM, one of the locking removal sockets can be easily used on them. Link to comment Share on other sites More sharing options...
