20 Pcs Black Heavy Duty L-Shaped Corner Brace Bracket - 50mmx50mm 90 Degree Angle Metal Shelf Bracket with Screws - Perfect for Furniture Repair, Shelving Support & DIY Projects

These are strong and adorable and got the job done! Would purchase again if needed.I wanted to use these brackets in front to accentuate the corners of some shelves I was making. This is a slightly different application than what most people would do which is to use them attached to the back of the project for reinforcement of the joint. But since I wanted to use them in front, I needed to purchase round headed screws separately as the flat headed screws provided stuck up too high and were sharp on the edge. The brackets were too thin such that I couldn’t drill a slight countersink for the flat heads to lie flush. Round head screws was the answer and were easy to get at a hardware store.I used these to reduce the wobble on some new Amazon Basic TV tables. They did the job fine. Reason for the one star deduction is that the screws that came with the brackets had a head that tapered, I guess typical wood screws which normally would be countersunk, but the braces were simply flat metal, so the screws stick out a bit. But, considering the price, this isn't fine woodworking, and they work.I purchased to reinforce a cheap set of shelves. Worked perfectly. Thick and durable. Fit well. Will purchase againI can't believe how thin these are. The listing states 2 millimeters so just keep that in mind because you're going to need to double these up if you want strength.Exactly what I needed greatGreat quality. And fast shipping. Highly recommend it.These are bad more for crafts small items mending wood
