Default metals and metallurgy thought for lugnuts.

I need new lugnuts for new rims the type with a washer on back and of course hexed front.

2.10- 2.97 depending on where i go and id need 20 (jeep xj)
so taking the medium at 2.5 thats 50 bucks for lugs.

I have a 5 ft bar of hexed 1inch 304 ss( 1inch flat to flat 1.13 measured on corners)

Stock lugnuts rust even the chrome ones so im assuming there some sorta junk steel carbon steel..

The question is would 304ss be stronger then the standard steel lugnuts? in my head i say ss is always stronger but obviously they make steel lugnuts for a reason?

Anyone happen to know there threads per inch or thread type/size for a jeep cherokee?

thanks for your time reading it

I would NEVER use SS for lug nuts. SS is gummy and will gall onto the studs, ultimately stripping out.

Size is probably a 1/2-20.

Unless you use something like a 17-4 or what ever it is that's heat treatable, you're just going to have issues.

304 is the suck for torque even as a washer. But don't listen to us. We are but immature teenagers

cant trust everything i google since theres facts to support both..what easily available material would work better then ss?....we never use 17-4 only common military/aerospace grade


*found out the reason they use steel galvanized for general lugnuts is the cost.....ss is still priced as a precious metal at alro .,..steel is not.

I would go with typical 01 tool steel, heat treat to desired hardness, tumble scaling off, and do a clear zinc

I bet ss is deemed a precious metal due to all the nickle in it

why spend 50 bucks on a material thats weaker then the one i can make?
And i dont drink..lol ...ever......................my rigs build not bought (not all my designs but throu member ideas and questions on the forums much like this one)

I dont agree with using galvanized junk steel .....stainless is better material....

plain old carbon steel or tool steel is my course plan now......Just my 2hrs alone i save 50+ bucks to put towards something i built not bought like ur rig:)

You need to do some more digging. SS is NOT stronger than all steels. Especially in the soft state. Do you know what type of material a commercial lug nut is made from? What it's hardened to? Neither do I but I know for a FACT that dead soft 304 would be worthless as a lug nut.

I've bought cheap lug nuts and had them fail. I've bought better quality lug nuts and never had a problem.

LOL @ this thread.

On one hand you have several people who work in the metal industry laying down facts, and then on the other hand, you got:

lol Ive never knurled steel before only titi and aluminum.......i honestly didnt see any numbers nor facts just personal opinions.

So thanks for the ideas and thoughts at this point im going to turn the lugs outta 304 and trial and error it..."fact" is 304 is stronger then any cold rolled steel ...Immortal/ rhino are right in the torque department thou......

been machining for 40+ years. do not use stainless for your lugnuts. buy some and never wonder what might happen, because you may not be alone when it all goes wrong! jmo.

Ahh, but you don't know what you don't know.

Making a statement like '304' is 'stronger' than any CRS is a pretty big leap.

The OP of this thread is prone to crack for wanting to do this. Just wanted to say that.

Just use anti-seize on them and create another thread if it is okay to use anti-seize on lugnuts.
