Exterior of the thumb nuts look as expected and have a reasonably good finish. The threads though are a bit rough, advise running a bolt into them with some lube the first time and then degrease after. One nut had threads missing from about 2/3 of one side of the threaded portion (See pic). I'm not even sure how that could happen...just threads full circumference about 1/3 in and then one side turns shinny with some light scratch marks where the threads should be...while the other side is threaded normal. I didn't return them...but did think about it.

Bought these to replace missing nuts for Advent speakers. They did not fit so I just replaced the screws on the speakers. Worked fine then.

I put an air filter on a 140mm fan in my entertainment stand using the supplied screws. It was a pain to remove and reinstall after cleaning with it being so close to the wall. I purchased some M4x40mm screws and these thumb nuts. Now it only takes me 10 minutes to remove, clean and reinstall the filter.

I used these to hold nylon bed retention brackets for my borosilicate glass bed. They were the perfect size - small enough so as not to hit the printer frame during print movement, but large enough to get a good grip on with my sausage fingers.

works fine but a little small to screw on
