40PCS L Bracket Corner Brace Sets, Stainless Steel Corner Brackets, 90 Degree Right Angle Bracket, Metal L Brackets for Shelves Wood Furniture Cabinet Chair Drawer with 80PCS Screws, Black (20mmx20mm)

Solid and sturdy corner brackets. These worked perfectly for reinforcing shelves and small furniture. The metal is thick and the screws included make installation easy. Once installed they hold everything firmly in place. Great value for the number of brackets included.

I got these to use for DIY projects that require cutting up 1x2x8 wood pieces. I made an air fryer stand using these, and they hold up pretty well. Comes in a pack of 40 pieces, and they are about 1.6 mm in thickness, 16 mm wide, and 19 mm in length. It also comes with 80 screws that can be drilled by hand with a screwdriver. The finish is rounded, which makes these safer to install in the long run. At only 15 cents apiece, including screws, this is solid in value without compromising on quality. Worth.

Gets the job done

btackets very sturdy. made from good heavy duty metal. Loved they came with screws. First thought was 5 stars. However, the screws kept breaking when put into wood (even tried pre-drill holes). Problem solved got heavier duty screws to work and saved enclosed screws for more simple projects. Therefore 4•

Not for heavy-duty but they work great for small things

I wanted to shore up the bottom of my kitchen sink cabinet and seen these which no store around me sells, not in black anyway and I didn't want them to shine like a diamond in the rough. I was impressed the package they came in is good enough to keep and the screws were also in their own separate bag. The brackets were held together with some twist tie keeping them nice and neat. I have nothing but good things to say about this product and with more shelves going up these are perfect because they are not thin but what I would call heavy duty that they can hold up some weight. The secret to j stalking these are you must use a centering drill bit, and if you don't have a set or never heard of them look them up and buy a set as your world will change. You will be drilling holes thru brackets and your screws will sit perfectly flush every time. I included photos of what they look like and how they function. This is also important when hanging a bracket such as this. If the screw is not sitting perfectly flush then you are going to sacrifice the workload the hinge can take. Look every screw is sitting perfectly flush with the bracket. They don't give you crap screws either they strip out or round them out. So these brackets have now given my shelf some considerable backbone because there are many cleaners and supplies under that sink and now I have 100% confidence these brackets which are considerably more expensive at the big orange box store will do the job they were hired to do, and yet will never get paid. My kind of worker. I don't purchase hardware online too often but I'll be looking more frequently because trying to find these in black just is not happening around here and not for what I paid.

Definitely did the job

The stainless steel brackets are sturdy, with a clean black coating. Screws included are adequate for light furniture, shelves, or box repairs. At 20mm they’re compact—best for smaller joints rather than heavy structural work. Verdict: Handy and reliable for DIY or furniture reinforcement.
