304 Stainless Steel Wing Nut Set M16 Butterfly Nut Hand Twist Fasteners Hardware 2PCS

These would not screw smoothly onto a bolt. I basically had to re-tap all but three of them in order for them to screw onto a bolt nicely. Very poor quality. They must have had debris or something in the threads. See photo.

Appear to be very high quality for the price, I was impressed

Used with a stainless steel threaded rod to secure a dresser top to a dresser base. Very well finished with no sharp edges, hence easy to undo if necessary.

Gets stuck whilst screwing on to a m16 bolt. I decided not to use for my project. Might need to be remachined.:(

Well made

Sturdy wing nuts. These are large enough to tighten without hurting your fingers.

Good quality!
