Recommendations for replacement lug nuts.

[SheepDog]

Great comment and good point!

Side note though, I can't believe that all I asked for was some recommendations on lug nuts and my thread turned into a torque pissing contest. I'm sorry everyone!!

Loving all the recommendations - keep it up!

Before I went the Titanium route, I hade these on. They too have a unique spline that a standard tuner spline socket won't work on, and come with a lock. The seat of the nut is on a bearing, so when it touches the wheel it doesn't spin and booger up the wheel as much. Perhaps gives a more accurate torque as well but don't quote me on that., but Im sure Professor Tony could confirm for us.

No need to be a dickhead. And many people don't torque aluminum wheels as high as steel wheels. Aluminum is softer. Do you know anything about metals?

You tell him no need to be a dick, while being a dick yourself. You are something else.

Do you know anything about speaking to people politely?

Edit: I read the rest of the thread and no you do not.

Site your source...

Very basic mechanical engineering principals dictate torque specs, based on exactly what @SheepDog said. Here it is, a nice Friday, I figured I'd sit down to a calm and informative discussion about lug nuts, having already been disappointed by the ridiculous garbage in the thread about 50W oil and, BAM!!!!

Has anyone tried the cone shaped advanced wheel locks ? After seeing how the mcguard did in this test I don't see the point. I only use wheel locks when I am staying at hotels.

LOL here I thought I was the only one shaking my head at the dumbfuckery in that other thread!

well, unless you use the finest Wisconsin Sharp white Cheddar as your wheel material.

Fastener and thus wheel clamp load is 9-15000 PSI with an advised range of >12k PSI which is 82MPa. If your nut cone seat is deforming the mating wheel surface, your wheel material is total shite or it was cut completely wrong.

Most alloy wheels are A356

Exactly. While I firmly respect the teachings that are handed down, as they generally have areas of applicability, there is a time to be open to continuing to learn.

To your point, given the compressive loads placed on an Aluminum wheel via a conical interface and the area the load spreads to support torsional loading, 150 ft lbs per lug isn’t that much given the diameter of the fastener, material type, HRc (of the stud), thread pitch etc.

Glemco, MatWeb, etc, are awesome online resources and the info is highly accurate. Looking at all the T6 rated Aluminum in the world, it’s amazing how many applications where it thrives with plenty of yield margin.

I was always taught with alloy wheels, torque to 100-105ftlbs, so have been doing mine to 105ftlbs for many years

Me too, 100 on my new Gorillas as I have done with all my cars over the last 30 years. Never had a lug nut loosen in all that time.

I have a serious hypothetical question for all of you who say under torquing is fine. I really hope that you will answer and answer honestly.
The question;
One of your closest family members is hit and seriously injured, maybe paralyzed or even killed, by a wheel that has come off another vehicle. It is later proven that the cause of the accident is that the wheel was knowingly under torqued by 1/3rd of its stated torque value. What do you do?

Come on guys, answer the question, I'm genuinely curious?
What would you do?

It's America. You sue!

But we have a vastly larger risk problem called Drunk driving, let alone Unlicensed, Uninsured, Untrained, and for good measure Undocumented. My uninsured coverage went up anywhere from 3x to 10x. That's not a outcome from people applying the torque figures for 1/2" fasteners to M14.

The proposed scenario from @ORRadtech has some street cred:



Furthermore, to avoid any quibbling over SAE or Metric, choose between 150 ft lbs or 200 Nm.

I replied but it didn’t post. Haynes has the spec at 100 for my wife’s C6 Grand Sport. Has anyone asked a tire repair place what they torque to? I’ve never had a lug nut come loose on any car I have ever had over the last 30 years. IMHO I personally would be concerned that a lug nut might snap off the stud at 150 more than one becoming loose at 100. That said, torque to 150 if if prefer. Now, let’s talk about the 10-2 steering wheel hand position.
