Review on 50PCS M3 5.4x5.4x2mm Stainless Steel Square Machine Screw Nuts Fastener by uxcell by Fuzzhead Nelson

Bought for use in the Petsfang mount I printed for an E3D V6 hotend. Others listed were either thicker or more expensive. From what I've learned from other reviews, thickness would be an issue so I wanted to make sure I got a thinner nut. They were tight as they should be, but they could be installed with a few taps of a small hammer, no nut or gasket modifications were required. Seems to be the perfect size for this type of application.
