Wheel studs

[Madgyver]

How long should they be?

I noticed these look kinda short, about 7/8" to be exact.

Mad, you should have at least 8 full turns of thread engagement between the lug nuts and the wheel stud, at which point the threads should be stronger than the tensile strength of the stud. Anything more than that is just gravy.

Since I assume the studs are 1/2-20, that means you have .05" axial travel per revolution, so you really only need .40" minimum thread engagement. The thickness of your wheel center and depth of the countersinks for the lug nuts will then determine your actual thread engagement. You can get extended snout lug nuts for additional thread engagement if needed assuming your wheels use 60 degree conical seat lug nuts, not something else.

Damn mag lugnuts screw up my studs.
Maybe these will work..

I think as long as the stud is at least flush with the outside of the nut when installed you should be good to go.

That's what had me notice it. I could see threads still exposed in the nut after torqueing it down.

I hope these work.

With a little sanding off the shoulder of the stud, I got this pressed in. Now to do the rest.

Are you using the same studs for the front and rear? I looked for longer studs for my slots but the fronts and rears were not the same (Chevy disc in front drums in rear). Some of the studs I found in the Dorman book were about the length I wanted but were not threaded all the way to the end so I was not really gaining anything. I'll have to check out the ones like you got.

Not trying to hijack, but it seems the knurlings are all over the place from what I see on the ARP and Moroso studs. Does anyone have a actual knurling size for the stock Ford 9" axles BB if it makes a difference? I actually stripped one on the front hubs trying to install with the washer and nut method.

Bump this up for wheel stud part numbers............

Pulling wheel studs in is a bad plan. They need to be pushed in. Be that with a hammer or a press. Pulling them yields or nearly yields them at the root of the threads right next to the start of the splines and severely shortens their life-span.
