The nuts on my downpipe looked sad and rusty , after porting my turbo and making a 3” downpipe I didn’t want to use rusty janky hardware but wasn’t going to spend a lot for what I needed , these look good , locked nice so I don’t have to worry about loosening and kept the copper finish after 3 months of hard driving and extremely hot days , I would recommend these to anyone looking for replacement turbo stud nuts

These were the highest quality high temp lock nuts for use on a Porsche catalytic converter exhaust. Very pleased and impressed with the complete transaction. I always use Amazon Prime whenever possible.

Looked for something to replace the chewed up header nuts on my 2013 Triumph Thruxton 900.... These were the right thread, had the self locking and the flange or whatever the part is called that's bigger than the nut....Anyway I painted them black and installed the newly painted headers (they were rusted and pitted) and they look great! I'll probably touch up the paint a little but otherwise they are doing great keeping my exhaust on my bike! lol

Haven't installed them yet. But they look nice. Was going to get stainless, but hadn't found any that had the locking tabs. Just serrated flange nuts. These should look slick on the bike, they better not rust if they are what they say they are. Get a little petina after a while. But that should buff out if I choose to. Will likely use some copper anti seize though.

A little different style than OEM but they worked perfectly on my 24v VR6 Eurovan. Way cheaper than original ones from the dealer.

They look nice and have the hexagon head size of 13mm that is better than 12mm
