100-Pack 2020 2040 2060 Roll in Spring Loaded T Nut M5 for 20x20 20 Series Aluminum Extrusions 6mm Slot Aluminum Profile Accessories (m5)

Good product

The spring detent ball holds these in place making it much easier to position and secure hardware to 2040 extrusion, especially when the extrusion is positioned vertically.

The product came quickly, but they do not fit the generic m3 profile in that the spring-loaded ball does not stick out far enough to get the nut not to slide on my generic aluminum extrusion. The force on the ball seems to be adequate for keeping it in place, but the spring-loaded ball itself does not stick out far enough to make contact with the extrusion. (I have a Creality CR-30). If this review does make it back to the manufacturer, make the spring-loaded thing stick out more.

Si possono posizionare benissimo sul profilato e non si muovono
