These worked alright, they are made of the cheapest metal you can find and will break if enough torque is put on them.

Bought these to put together a desk I was making and it was just what I needed. I got 2 packs of these and used more than I thought I was going to but worked great!

I got the "20 Set Black 4040 Series with M8 screw nut" and both brackets and 8mm bolts were fine; however, the T-nuts were way too wide at the bottom of the nut to fit any of my 4040 extruded tubing. I ended up using separately purchased carriage bolts and nylon-insert nuts that I had on hand. Seller contacted me to correct for the error. This would have been five-stars if the nuts where correct, I gave 4-stars because rest of product was rock on and seller actually cared.

The brackets and 8mm bolts were fine, but the t nuts were too wide to fit my 4040. luckily i had a bag of them from a different vendor. Seller contacted me after my first review and offered a full refund, and said they would address the issue with their supplier

These work great and are much cheaper than other brackets. Though the nuts did need to be grinded down to fit in 1545 aluminum from tnutz.

This is a great 2020 part. Haven't had any problems with them.

I am so glad that I bought these corner brackets. These have extra details to keep them from rotating once they are inserted. The silver sliding T-nuts for the screws also do not spin once inserted. Additionally, they are large enough to keep from spinning out of position or completely fall out of the aluminum extrusions. I successfully built my sink counter/cabinet frame using only these corner connectors. This is my first attempt of building this simple frame with the 2020 series aluminum for my camper van. I will add a shelf and then cover the frame with thin plywood sheets later.
