10pcs Corner Bracket Plate Black 2020 Series 5 Hole L Shape Joint Plates with 50pcs M5 T Nuts + 50pcs M5x8mm Screws + 1pcs Wrench for Slot 6mm 20S Aluminum Rail Accessories (10PCS L Shape)

I was able to build a speaker and projector stand with these brackets and did not even worry about the weight! they are very robust and easy to use. Make assembling very easy and adjustments are just a matter of loosening the screws a little.

Whatever 2020 extrusion thingamajig you're adding these to will become built like a tank. Plenty of screws to secure them using all 5 holes. I got two packs to stiffen up an Ender 5 Plus. Very happy with them.

Got this for making enclosure for printer,Use lock tight or clamps when tightening for perfect angle

Solid product, works great with standard 20 extrusion profiles. Very good value.

This review is for the 2020 Aluminum corner brackets with screws and t-nuts. I checked for magnetism, and the screws were strongly magnetic. I didn't try to rust one, but it looks shiny enough, I'd say it's a chromium based stainless steel (Nickle alloy isn't magnetic or only very weakly so). This indicates a much higher quality than most hardware I get through Vine. Everything looked good and correctly machined. There were extremely slight tooling marks on about 10% of the pieces, but they were very slight. You'd have to be looking really hard for them, or need very high tolerances, for this to be any kind of concern. They were all on one side, so aesthetically, easy to hide.Packaging were resealable ziplock bags, and several layers of packing paper between the extrusions. Each type of hardware was separated out.I'd recommend these.

This was a nice kit of mounting plates for 2020 extruded aluminum construction. The plates had a fairly matte surface texture, with no burrs or other issues. In addition to the 10 plates, more than enough screws and nuts to quickly assemble some structures with the extruded aluminum. An included fallen key is a nice touch, even if not needed for me but one additional detail I liked a lot was the use of small ziplock bags for holding the screws and nuts. Being able to reuse those bags is so much better than the rip-to-open shipping bags I often see used in kits with similar quantity and quality of parts.The only thing you might want to be aware of if going for this kit is that the included nuts, while functional with the 2020 extruded aluminum is that then need to travel from the open edge of the extruded aluminum, these nuts were too wide to drop into place and then rotated as the screws are tightened, however for me and my current project, that wasn't a deal breaker.

The media could not be loaded.  I have laser engravers and 3d printers as well as I know desktop cnc machines likes to use aluminum extrusions these work well for modifications on these things as well as they came with matching hardware.

They come with t-Nuts that you need to slide in the groove not the one you can twist into place. This can make assembly a challenge in some cases but those T-Nuts are also sturdier.

Excellent!

Good

Only complaint and reason behind 4 stars and not 5 is the t slot nuts are the kind that you've gotta slide in and not drop in

I used these in a 3d printer mod. They worked, but I should have paid attention to the size, they could have been a bit smaller.....
