Flanged Exhaust nuts, Anyone use these? Options

[jeffdon]

Flanged nuts that take a 10mm socket. This sounds WAY easier to work with. Anyone try them?

I bought a box of 100 similar ones made of copper back quite a few years ago from a repair shop in Nebraska.

Wish I bought 2 boxes (IMG:style_emoticons/default/smoke.gif)

I agree with reharvey,needs washers for SS exchangers

I seriously doubt the nuts you bought were copper, which would be a really poor choice of material for nut. Way too soft, it would be likely to round off while being tightened, or to fracture if it were hardened. They were most likely the everyday 12 or 13mm wrench size copper plated steel locking exhaust nuts used on BMWs and some water cooled VWs. Porsche and VW never used locking exhaust nuts on air cooled engines, and I don't recommend the use of such hardware at my shop.

I used to use those nuts as well, and they're solid copper. You're right, they're soft and easy to round. I think they're an alloy though, because they are harder than regular electrical wire copper. You still only get a use or two but they don't rust like most other nuts, so it's a tradeoff.

They're German, aftermarket not OEM, and big in the VW scene, so I'm surprised they never showed up in your shop. The ones from Aircooled.net are better.
