Nutty question: What is the torque for lug nuts

[75USCarrera]

Is there a torque value I should use for tightening lug nuts on a 75 Carrera with Fuchs?

Maybe you meant 1,152 in-lbs (?????). Just kidding, got too much time to spend these days because of the snow storm we had yesterday.

aha - now I see why this thread has gone on for days...

I will vote for 13.2725 kp-m

BTW - that's N-m, not N*m... or use a raised dot.

dyn-cm is still available...

Thanks All

what's wrong with N*m or N x m?

This is the textbook thread for how this forum works. Gotta love it!

not an allowable abbreviation sez the editors of certain scientific journals I will not mention

Two grunts. One and a half if you are using anti-seize.
Do a search to find out how many foot pounds are in one grunt... You'd be amazed how much info is already available.

A question related to this thread...

What socket are you guys using for the nuts?
Are the Nylon/Plastic insert type in our sponsors catalogue any good?

I like the idea of having fresh looking nuts

Actually the lug nut torque for your car is 13 kpm (130 Nm). To convert kpm to lb/ft multiply kpm (13) x 7.23 = 94 lb/ft. The 13 kpm (kilopondmeter) number can be found on page 66 of the Porsche Spec Book for 1975 Models.

You can get excellent results from the "soft" sockets. They don't allow you to get away from using an impact wrench, though.

Thanks for the reply.

I use a 1/2 inch drive Snapon torque wrench on my lug nuts.
It's so easy to use I'm not sure why anybody would use an impact wrench.
Just one lovely "click" is all it takes...

[Peter Zimmermann]

I am sure Milt meant to never use a soft-socket for impact wrench removal. Never use a soft socket with an impact wrench, it will tear up the socket.

Mac, SnapOn and probably others make 19mm impact sockets that have broached (rounded) internal corners. They are great for nut removal with an impact wrench, but if your nuts are concours-level only removal with hand tools will keep them looking good.

Yes.
