Lug nuts

[Nick in Fayetteville]

What is the correct torque for lug nuts? I have heard from 45 to 55. Can't find any info in Ford Barn records. I know that Ford didn't have torque specs published during the Model A era. Thanks....

Convention is to torque to 50-60 or to do it by feel, both seem to work equally well. The main thing to watch out for is that, if this is being done on freshly powder-coated wheels, the powder will compress slowly under the nut. So, much like head nuts, one should re-torque and check several times until they stabilize.

Why are they called lug nuts? Answer: Originally the wheels on cars were not removed to fix a flat. The tires were fixed on the car. Then removable rims were introduced. The rims were held on my lugs which were held on by lug nuts. Now we have removable wheels but the nuts are still called lug nuts.

Alternate the tightening sequence, every other one. Increase pressue eachbtime around. Tighten till they’re tight, and afterwards check often. In 60 years of driving my A’s i’ve never used a torque wrench on my wheels.
