Stainless Steel Lug Nuts?

If you look at the link where the lug nuts are sold you will see that customers who bought the nuts also bought Anti-seize thread lube......

It would be a must,,,, and the threads would still be subject to galling and seizure at a reduced rate.

My experience has been that stainless is no good for high tension fasteners, and this is even more true as the diameter of the fastener increases.

Imagine yourself on the side of the road with a flat tire.... And one or two lugs..... Anyway, my bet is that if a person uses these leg nuts without anti-seize every single one would be terminally galled to the point where not only the nuts would be trash, but all of the studs as well.

I think stainless is too brittle for threads. My theory is that the sharp tip of the thread starts fracturing off, clogging the path causing more fractures,,,, the result is that the fastener tightens ok,,, but becomes irreparably jammed up in the first two or three turns on removal.

It is a sickening feeling. And nothing I have ever seen locks up so tight.

Stainless fasteners are pretty, but there is a huge downside.

Take a look at the picture. See the large bolts that hold the suspension at the ends of the bars?

I thought those would be cool in stainless.

On the first mock assembly I had a friend who installed the axle while I went to buy a bottle of anti-seize...

I stated at least three times to leave the nuts finger tight...

He tightened them....

Do you have any idea how hard it was to break those 5/8" bolts?

Stainless can be made strong but it costs more and corrosion resistance goes down as strength goes up. Stainless is used all the time in aerospace but you don't want to pay $1000 for a set of lug nuts. Cheap stainless like they make sinks out of is weak and soft. If a magnet sticks to it you know it is cheap. Stainless also does not crack as easy as most steels.

Please don't use any lubricant on lugs.

In my experience, if anti-seize is not used, stainless lug nuts will be "tighten once" and then break off, and replace all wheel studs.

Like I said, I would never use stainless lug nuts or recommend that anyone does.

While I would not recommend using lube on lug nuts, I doubt they would back off. There are too many engine fasteners that defy this idea. (I.e. Connecting rod bolts and main bearing caps. )

Unless specified in the torque value chart for a particular engine, no lube or anti-seize for head, intake, mains, nor rods either. Torque values will be off if you don't follow specs for lube or no lube.

Stainless lugs nuts are a bad idea....I'm, quite frankly, surprised they are available. I wonder if those who think they have stainless, have good quality chromed steel.

Stainless Steel Lug Nuts?

I am aware of the inherent issues with stainless steel seizing, many years working on boats. If the S/S fasteners and surface are not square the threads will stretch/distort & then it's time for the Dremel. Not fun. For wheels, only the lug nuts would be stainless, also I think the tapered seat of the wheels and tapered lugs will mitigate this problem.

The S/S lugs for boat trailers don't have the bulge on them. To me that 'bulge' looks like a way to increase surface area to disperse stress, just a guess on my part.

I think any type of lubricant on lug nuts is not a good idea.

My reason for the post is to find out if S/S is a possible solution & what issues exist. Also how have others solved rusting lug nut issues, they just look ugly on nice wheels. I check torque often, that's a lot of contact between the lugs & a socket, chrome has not worked for me. Wax has not seemed to help either.

Get the McGards referenced above. High quality chrome. I've had mine for 4 years. Look good.

Torque angle fasteners, ARP stud kits, etc. are often specified to be done with lubricant these days, and in any case the threads on these fasteners always become fully saturated in use.

Oil will alter torque values, but I don't think it will cause fasteners to back off, but I reserve the right to be wrong.

Right, we're in agreement. Back to lug nuts. To the best of my knowledge, no one recommends their lug nuts to be lubed before torquing. If you do, even with anti seize, you may very well actually over-torque the nut while torquing to the recommended spec....possibly stretching the lug to the point of eventual failure after repeated re-torques and pothole hits, for example. Backing off....maybe, but also maybe not likely.

You might consider aluminum anodized lug nuts. This is what Porsche uses on all their cars and the loads are much greater than an AS. But what ever you choose make sure
you brush on a light coat of marine Neversez If you end up with any corrosion you are toast

Stainless Steel Lug Nuts?

I never thought of anodized aluminum, interesting. Just searched for them, they are not inexpensive.

This has been helpful. Going to a Discount Tire store in the am, they say they have S/S lug nuts for my application with a lifetime warranty. I'll post my thoughts, opinion after I see what they have.

Porsche never puts cheap bits on their cars. However their engineers over think everything

If you want light and tight, Titanium Lug nuts and studs can be found. In all cases I would use the "Airstream Ball Lube" to make them shiny and seize proof.
