Pack of 100 Rolls 2020 2040 2060 Spring Loaded T Nut M5 for 20 x 20 Series 20 Extrusions Aluminium 6 mm Lock Aluminium Profile Accessories (M5)

Good quality and works perfectly as intended

At this price point you expect a few duff units in a pack but there are surprisingly few. I prefer these over the half nuts that can screw themselves out, but these still have the advantage of being able to add into a channel retrospectively. They can still slide around when loose and the channel is vertical say but overall tend to stay in place until moved into position.

as described, can't fault

Not compatible with the 2020 profile I have which was also sourced from Amazon. Firstly, the spring loaded balls did not protrude deep enough, so were entirely innefective. Secondly, the flanges were not wide enough meaning that the fasteners were only hanging on by the skin of their teeth. Sadly, an all round failure.

Whilst I am not, normally, forthcoming in giving a review I have found these tension T-slot nuts so much easier to use and manipulate into position compared to those with a spring "clip" that required much more force with the potential to break the clip making the nut useless. I would, therefore, highly recommend these T-nuts.

These T nuts are just perfect. Many don't hold but these are great with the ball bearing springs and can be inserted without having to slide in from the end but once in, orientate themselves correctly and do not fall out. Definitely the ones to buy for 20/20 profile

The entire point of the spring ball is to keep them from moving in channels. these are loose so using them for vertical channel will not be suitable.

Unfortunately I've tested over half of these in the package and so far only half of them actually stay in the slot and not fall down instantly.

Si possono posizionare benissimo sul profilato e non si muovono

I saw quite a few reviews saying that these "wouldn't roll in as advertised. I had no problem getting then and and staying in place. The secret was to use a tool...specifically a long 5mm screw turned into the nut threads , fully engaged but not past the back side. That allowed me just enough oomph to get these to snap into place pronto. You have to get one side just below the flange of the extrusion and then rotate it. It doesn't feel like it will fit but only a little force popped it right in. I am loving the fact that they don't slide around as you make you connections, but sliding it into position after the screw is in but not tightened was as easy as 3.1416 pi ! Good product. I will definitely buy again as the need arises.

Die gebotene Leistung und Menge passt sehr gut zum Preis und eine klare Empfehlung meinerseits

About 10 out of 100 were broken or didn't fit in the rails. But this is to be expected and I have bought worse quality t-nuts. Happy with them!

Sauber gearbeitet und passt perfekt
