12 Pcs Car Exhaust Manifold Nuts Head Copper Nut M8 Hex Nuts Copper Self Locking Car Parts for Bmw E30 3 Series

Good quality

Work perfectly for the job I needed them for.

Exhaust job. Good piece of hardware. That's it.

Bought for a Corsa D exhaust section I was replacing, item was as expected good quality replacement nuts which are a popular size so will have spare to keep in my toolbox.

Fit’s Vauxhall Adam.

As expected good quality - Thanks

Bought these to use as new nuts for my R125 as the second stud bolt just snapped. Ive repaired both studs by retapping them up a couple mm and thought I could try prevent corrosion by using copper nuts. So hopefully, they shouldn't stay too tight when I need to remove the exhaust which unfortunately is every time the oil is changed (3k miles) as the exhaust covers the drain bolt.
