10pcs Aluminum Alloy T Slot L Shape Joining Plate and 50pcs M5x8 Hex Screw and 50pcs T Nut for 2020 Series Aluminum Profile

I purchased these to add support to my newest 3D printers frame and they were absolutely perfect for my needs. They are all machined very cleanly, no burrs, no hole issues. The screw were all in good shape. It fit perfectly straight on the extrusion, no corners being up or out of alignment. If you need to stop something from vibrating these will do the trick, they are very sturdy.

Worked perfectly for the Z-axis top of my CR-10S. Fit the horizontal and vertical extrusion bars, but you must mount only the inside 2 to ensure tooth nut parts are straight and holding the bar extrusion parts. Then the do the 2nd ones, then the outside end ones. That way it's holding all of the parts just right. You have to hold the 2 sides to ensure they are perfectly aligned with the horizontal and vertical extrusions. A bit of work to do, but you only have to do it once!

Works well with the T-Track 80/20 rails.

Update:Seller was very responsive to correct the discrepancy between the picture and the description. I’m happy with the outcome and hoping the pictures get updated.Original review:The ONLY reason I went with this item over others is due to the picture showing the plate is 0.21"(5.4mm) thick. The description is correct of the item being only 0.16"(4mm) thick. Really needed the added thickness for my application. Disappointing for sure.

These do not fit 1.5x1.5" t-slot 8020 aluminum extrusion. I am not sure what these are actually intended to fit but the screws are not even remotely close to being long enough to work on real t-slot 8020. Backing pieces strip super easily even if they were long enough.

The brackets are high quality, well made and honestly.. perfect! The screws are a little short but manageable and work. The backing nuts are crap! They are very small, do not fit the extrusion well and the shoulder is almost nonexistent! I happened to have extra backing nuts so I did not return. Not sure I’d order again.

Perfectly functional. Seem to be accurately machined.

These are high quality that you can rely on.

I have these in use, but for the 600 mm 2020 arms, forming a cube, which they are bracing, I will use a sheet of metal to close the open faces of the cube!

Well-crafted, strong, does exactly what's needed.

The media could not be loaded. The T-Slot inserts included do not fit 20/20 extrusion. Do not recommend.
