most lugs are forged right?
aftermarket extended ones are too?

i was thinking about doing a production test run of 7075 AL lugs in 19mm, to see if i could get the cost down from the 70-80$ a set. theyd be longer for ex studs too. made by cnc

would this method be worse than any other company?
i dont want to have to worry about liability.

I belive using billet peices would be stronger than forge shaped peices. But like you might have noticed they will cost more as well.

im thinking of getting them CNC's from AL stock

Aluminum lugs? They are going to gall like hell and you'll never get them back off.

most porsches use al lug nnuts stock...im not so sure about galling

beepy

Those nuts are hard anodized which will prevent galling. But if you machine them yourself and don't anodize them....

7075 is like the second hardest AL next to 7068.

i dont think theyll mess up but ill talk to my machinist

anyone else?

Anodizing is simply a surface treatment. it in no way adds to the strength of the product, it is mainly for apperance and surface protection. On a lug nut application it would be stripped off quickly even by just threading the nut on!

I suggest raw 7075 aluminum. Hybrid PM me, i may be able to work out a low price.

pm'd but i have found a really good production cnc shop that is making shift ***** for me now, but ill entertain your price incase.

get them "hard" anodized .. companies do this to suspension components . its a thicker stronger anodizing . ive only seen it in black tho .. dose not scrape off like the fuel fittng aluminum coatings .

anyone else?

Black anodizing is normally 18 micron. I don't think it adds any strength to the part, just a hard, more corrosion, scratch and chip resistant.

dfoxengr

that makes sense ^^^

Anodizing definitely adds surface hardness. Anyone remember when STR cam gears first came out? The outer ring was not anodized and would wear very badly and chew up the timing belt in no time!
