I would never tighten a bolt with an impact wrench. You have no idea how much torque you are appling.

Cliff - with a 4' lever on the socket and guessing you are putting your weight of 100 to 150 lbs on the end of the lever which means you are putting between 400 and 600 ft-lbs of torque on the lug bolts. I don't have my charts handy but that is way too much torque. just my 2 cents.

I agree with Jim's comments. From other Cord guys who are no longer with us, the generally accepted torque is 90 Ft Lbs. I use a tension wrench just for peace of mind. After tightening them I drive the car without the hubcaps for a while then recheck the wheels nut with the torque wrench. Some nuts have moved a little and tighten up then the hubcaps are refitted.

I agree that 90 ft-lbs is the correct torque. I believe Josh Malks recommended this also. I remove the bolts with a gun, but tighten them by hand so as to not over tighten or damage anything.

Every vintage car owner should own a torque wrench. Use it to install wheels then re-torque after driving. This is the routine on modern cars. 90 Ft lbs
is a good spec.

Ok, got it. Will only use the impact to remove the bolts. I'm wondering how long it will be before you can set the torque on one of them.

Here are the 7/8 NAPA head lugs next to the originals. The NAPA lugs are 1" of thread vs 3/4 for the originals so I'm going to see if they come shorter as I would rather not cut them.

They do seat much better than the originals.
