Default Lug nuts

Did I read the lug nut should be 77 foot pounds?

You may have read that somewhere, but, 50-55 is better. Your studs may not like the 77.

Threaded fasteners can all be torqued to standard specs for the diameter and thread pitch of the joint. There are exceptions to some but it depends on how hard the material is. A rear axle is a good example.

And lest we forget, torquing is usually specified "lubricated' which gives a more consistent final torque.

The length of the off set on the Ford lug/starting wrench will only allow so much torque when using it, unless you strong arm it. They only need to be tight enough to keep them in place, not deflect the center pulling it down into contact with the drum at the mounting holes. (If you look at the back side, the area around the hole is not flat it has a shoulder) The mounting holes on the Model A wheel were not made to be in contact with the drum. They act like a spring, keeping the lug nut from backing off. Without forcing it, put the wheels on using the Ford lug/starter wrench then use a beam type torque wrench and see what the value is. The cross sections I have seen with the wheel installed show about a 1/16" clearance between the hole shoulder and drum.

When replacing a wheel the other day I used the Crank/Lug Wrench to tighten the lugs. Using very strong pressure on the wrench I got out the Torque wrench and checked and all lugs were just about 55 lb-ft. The right tool for the job

Just remember that the impact wrench was not invented yet so everything was done by hand and that was sufficient.

Rather than concentrate on getting them so tight, just check them every so often. Just takes a minute or two.

I've never seen a too tight engine last very long or go very fast . Over tightening causes friction and heat !!!!!!!

Ahhhhh, sooooo purdy if I tighten my lug nuts at 2 lbs, that equals very little friction, I then would go wicked fast.
