100 Pieces 2020 Series T Nuts, M5 T Slot Nut Hammer Head Fastener Nut for Aluminum Profile

Having a Laser engraver, two 3d printers and a bench top CNC machine make these indispensable! They never seem to include any extras so adding or enhancing features are more difficult. Now with these this is no longer a problem and the several different sizes that are included ensure I will have what I need.

This is an affordable variety pack that I have used on my 2020 and 2040 extrusions for my 3D printer. I have been able to add braces and a variety of tool holders with these at my disposal. I also plan to use these for my desktop CNC as I continue to work on that project. Love the fact that there are 3 bolt sizes.I recently had to add these as support to a tool holder that was sliding on me. The M5 t-nut was a great pair with the M5 bolt since it was large than the extrusion opening without being attached to something. I was able to use them as a "shelf" of sorts to keep the object from sliding down on me.These are always good to have around, especially when you are working around extrusion on a regular basis and are in need of quick, easy solutions. Well worth the small price tag to have these on hand!

They're fairly malleable, but they work pretty well.

Bought for the 3D printer and they are great....

There were just what I needed to make some additions to the frames of my 3D printer

I initially purchased these hoping to use them to mount a few things on my 3D printers (CR-10 and Ender 5/5 Pro), so I decided to give these a shot and they didn't disappoint. They worked as intended and seem pretty solid as I haven't had anything slipping. Overall it's pretty good quality and quantity for a good price, which makes for a great value overall as long as you plan on using the different sizes.Only negative isn't really a downside but more of a suggestion for the manufacturer. Personally, I'm not a huge fan of purchasing variety packs of things like this since I usually end up not using some of the items. It would be nice to have other options/portions, like being able to purchase a variety pack of JUST M3 and M4 sizes. Or it would be nice for this manufacturer to offer these individually since they didn't appear to offer the option to purchase them individually.

They didn't fit my 2020 extrusion purchased from McMaster Carr. Edit: I suspect McMaster uses 3/8" trail in place of 20mm. The issue is that the slot is much smaller. After opening up the slot to 1/4" on the mill, they worked perfectly. Wish they were cross compatible, but this is fine, too.

I bought these under the impression they functioned the same as the slide in nuts and then found that they can be inserted ( and fall out of) the 2020 slot from the front. It takes some time to get used to, but they do work. As you tighten them, they will begin to turn, orienting themselves from vertically to horizontally in the slot. I gave this 4 stars because they can be reluctant to align themselves. I think a slightly steeper radius on the shoulder would do better to guide the nuts into self-alignment
