KOOTANS10Set 2020Series 2 Hole 90 Degree Inside Corner Bracket Kit, Black L Corner Bracket for 2020 Aluminum Extrusion Profile 6mm Slot with 20pcs M5 T Nuts, 20pcs M5 Hex Screw, 1pcs Wrench

I previously had bought a tall and super cheap bookshelf that has no backing on it. The thing was cute but came with no body support. This bookshelf would sway and lean over soo bad... that I thought it was literally gonna collapse in half one day. I couldn't even move it around.I eventually came to the conclusion that I was gonna have to trash it and buy something higher priced... but I wanted to try one last ditch effort to save it. I went online to find something to stop the swaying then I came across this item. I applied it to the middle backside of the shelf and at the bottom.And I tell you... these brackets are AMAZING!!! NOT ONLY HAVE THEY COMPLETELY STOPPED THE SWAYING.... but have added soo much body support and sturdiness... that I can push the bookshelf from one side of the room to the other and it will not even bend. LOVE IT!!! THEY HAVE ABSOLUTELY SAVED MY BOOKSHELF!!!

Works great connecting 4040 aluminum extrusions

Used the hardware for a custom laser enclosure. Really awesome products.

While some of the screws and T nuts are a little crunchy, the plates are well made. Working great for adding some Z axis support to my SV04.

I needed these for a minor modifications to a laser engraver I ordered recently. These brackets and included screws and T-nuts worked perfectly. The fit was absolutely flush on the surface. I was definitely pleased with the threaded hardware as well. I did not encounter any jamming or cross-threading. The T-nuts worked better than I could have imagined. I was able to create the modifications with no problems at all. The amount of angle brackets included in this kit was perfect for my needs, and an amazing value for the money. The local hardware stores just don't have the specialized hardware that I need.

These brackets are precision machined with no burrs or tool marks such as sear marks or punch flaring at the holes. Perfectly smooth. Material is heavy aluminum plate stock. Finish is satin, and I assumed, passivated with clear iridite or anodized. I used them as-is, but the surface is ready for painting if you like. Price-point is excellent especially considering you receive the hardware (with correct t-nuts) to install these with five bolts in 2020 extrusions. My cube printer is extremely rigid with these added partsHighly recommended.

The product quality is good. No sharp edges. Consistent finish.First set I ordered had all of the hardware. Second set missing 6 screws. As you can see from the photo there are 6 nuts but no mating screws. One screw the hex was bad, but most likely not the suppliers problem.Update: 7/30/21The seller contacted me and immediately resolved the issue. Excellent customer service. I highly recommend and would rebuy from them.

Cabinet for gas range top unit I purchased is stronger and can offer years of use to new cabinet install.

Well finished Delta plates, clean threaded anchors and machine screws.

Great price
