Sturdy and quality built corner brackets for small to medium DIY projects
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.

Great thick quality
These were great and sturdy. I accidentally ordered the wrong size and had to return them, however the quality of these brackets are great.

Strong brackets for small wood projects
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.

Recommend for light/medium duty use. Solid product
I ordered these corner braces to secure shelving to the floor. Overall they work pretty well however I would say they are not the most heavy duty ones ive used. That being said, the price isnt heavy duty either. Id recommend these for light/medium duty shelving as they have come in clutch in that regard. They are quite easy to install and look pretty nice as well. Overall a solid product for a decent price

Exactly What I Needed
The cheap plastic brackets broke off a dresser so I repaired it using these. The only down side would be that you have to buy 40 when you need 3. For the price, it was worth it to be able to use the dresser again.

Heavy duty thick brackets. Full trust in their strength to hold weight.
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.
