24 PCS Female Thread Nuts Clamping Star Knob, Plastic Hex Shaped Handle Black Clamping Nuts, Knurled Quick Removal Clamping Screw Nuts Knob (M4,M6,M8,M10)

The price was reasonable, the only negative, is on one of the 10mm knobs didn’t have internal threads on the inserts. Other then that, I’m very satisfied.

Really not good. None of the M6 knobs (the ones I need) line up straight when threaded on the screw. Only two of the eight included M6 knobs are what I consider good enough to use. I need four.It's like I received a box of rejects. I have to return them.
