10pcs 2020 Aluminum Extrusion Joint Plate Connector Corner L Bracket 8020 V Slot Hardware T Slot Accessories with T Nuts and Screws for Aluminum Profile 3D Printer Frame Black

These 2020 aluminum extrusion corner brackets by SEEKLINY are well built and sturdy. They have t-nuts molded into the arms and use a set screw to tighten the bracket to the extrusion. Tightening the setscrews does scar the extrusion’s trackway, but the damage is minor. There are other styles of corner brackets that make similar connections, however if you are adding a panel to the extrusion project, this form of corner bracket is likely to be the easiest to work around. This offering comes with 24 brackets, 48 set screws and a hex wrench. The set I received had a few extra screws. These brackets are very handy when you work on a 2020 extrusion project.

I ordered the Seekliny 2020 L Corner Brackets for my project.The plates and screws worked great, the nuts require a bit of a learning curve.While securing the screw to the nut, the nut can rotate - which, if it does, leaves less of a surface to secure to the T rail of the aluminum extrusion, and the mount will not hold.To remedy this, I used a tiny flat head to help keep the screw from rotating out of position while I secured it with the hex wrench.Despite the painstakingly long process of getting these secured to my T rail, once installed, the brackets are very solid. I used my mount in a moving vehicle over the course of a week, and while other reinforcements (inside corner brackets and 3-way corner brackets) failed, these did not.A 3mm hex bit quickens the installation process.

This kit comes with 10 brackets, and a set of T-nuts and Allen screws, all in Metric. I have used Inch size 80/20 extrusion for some time on different projects. Although this kit is in Metric, it worked well making a connection between two pieces of the 1 inch extrusion.The T-nuts are stainless and would slip into the extrusion slot and turn to lock in place when the allen screw was tightened with the included key and was sized to also work in the 80/20 brand slot. They held very well and made a very strong connection. The distance between the holes is less than an inch so there may be some applications these would not work for, it does not make much of a difference in this connection application and this kit is way less than a brand name similar bracket.The brackets look good and seem to be made from aluminum. I think it is a powder-coated finish instead of anodizing but looks good no matter what it is.Recommended.

If you're looking to build some structures with 2020 extruded these joint plates can help out. Seekliny is a generic brand but there's nothing to complain about. The plates are dimensionally correct, with no rough spots and a decent matte finish. The nuts included are the drop-in variety that can be useful for updates or addons after the main structure is built, just as they can be used in the initial assembly.

Nice strong brackets. Includes plenty of hardware. The black coating is well applied. Will help to keep my printer frames sturdy and in line.

These are decent brackets. Not steel, but still pretty decent. This pile of brackets comes with mounting hardware. The nuts are the cheaper ones that, to me, are a little bit fiddly to get right. I prefer the ones with the little spring mounted ball bearing. Even so, dees nuts work fine, just not in that pleasing way of the ones I like. The dimensions and all are fine and I suppose that aluminum brackets is fine for 2020 – I mostly use 4040 and 8020 with the beefier hardware for beefier structures. Regardless, these work.

The L-brackets fit in the 2020 extrusion I am using, and the set-screws work good. They are able to move around and then tighten, so it's fairly easy to adjust things. It came with 2 Allen wrenches which is nice, though I already have a bunch lying around. Good set, I'm happy!
