## Description

Package Content: 10pcs 20mm 90 Degree Solid Cast Aluminum Corner Bracket, 20×28×28mm (0.78″x1.1″x1.1″). 20pcs Carbon Steel Galvanized M5 T-slot Slide Nuts. 20pcs Black M5 x 8mm Hex Socket Cap Screw Bolt. 1 piece 3mm wrench.

Review: Received M6 bolts and nuts. Didn't fit the extrusion. - Despite the description of M5 nuts and bolts, I received M6. The T nuts fit the 2020, but the M6 bolts would not fit through the slot to reach the nut. I kept the brackets and just used some M5 bolts and hammer nuts that I had on hand. Probably should have returned them, but not worth the effort.
Review: Make sure you look into how your going to use it and possibly buy some longer m5 bolts - The cleats on the surfaces that it mounts to probably helps in some applications like a 2020 connection to another 2020 extrusion but the side of a 2080 to a 2040 sideways didn't help out I should grind them off as it would make the braket sit better as well as the original m5 bolt would work but I had to buy longer m5 bolts to get it to work.

### ⭐⭐⭐ Make sure you look into how your going to use it and possibly buy some longer m5 bolts
*by R***T on 9 August 2022*

The cleats on the surfaces that it mounts to probably helps in some applications like a 2020 connection to another 2020 extrusion but the side of a 2080 to a 2040 sideways didn't help out I should grind them off as it would make the braket sit better as well as the original m5 bolt would work but I had to buy longer m5 bolts to get it to work.

### ⭐⭐⭐ Screws will rust over time
*by B***R on 21 February 2023*

The screws in the kit will rust over time if you are in a humid environment. They are not aluminum. Now I am looking for a stainless version…
