Boeray 2020s M3 T Spring Nut: Half Round Roll-in 🔩 Tee Nuts for T-Slot Aluminum Profile 20x20mm - Pack of 50pcs Review

T nut is not for 2020 aluminum profile with 6mm slot but for aluminum profile with 5mm slot. As you can see in the picture, it fits very badly into the slot, basically useless for me.

This is a decent product, the sizing is a little different than the 80/20 sizes so you'll have to wrestle a bit to make them work, but for the price it's ok.

These nuts really are the right choice for aluminum extrusions. You can easily insert and remove it. It stays in place when you loosen the screws.

If you work with T-slot profiles, they are a must. If you've only been using plain T-Nuts, you really need to get them, and you'll never use plain nuts ever again.

Almost right. Using Openbuilds extrusions. 20mm x XXmm. slides out easier than Openbuild's spring-loaded M5 T-Nut, but still holds the screw and object under load.

I bought this for my TeVo tarantula because I was tired of messing with the nuts that came with the kit. Makes a set that requires a lot of love and attention and is a lot easier to manage. One of the must-have items for inexpensive T-slot kits.
