They look good and work as intended.
When fixing up an old car, I don't really like to use a lot of hardware store fasteners because they just don't look right. Most cars use flanged fasteners like this and that is why I bought them. They manage to do the job well and look stock, without having the tendency to tarnish and rust that you see in stock zinc plated hardware. So yes, I would buy them again and have bought several different types of hardware from this seller to use on my cars because I really like the way they look. It seems like a small detail, but those small details are the difference between looking right and not quite right.

Great value!
Ordered these SS nuts to use on an RV tank replacement project I was doing. They fit well and quality seems to be very good. Can't beat the price as this is what I would've paid for 4-6 at the big box stores.
