Review: 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.
Review: 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.

## Questions & Answers

**Q: Are the edges of these brackets smooth?**
A: The quality of these brackets exceeded my expectations, sturdy construction, smooth and burr-free, and the included screws are of excellent quality. Perfect fit to my cabinet corner braces. very easy to install. Would recommend, and buy again.

**Q: I'm afraid to use the screws that come with these brackets. What size did you use to replace them - #6, #7, #8?**
A: The screws were just the right depth and had no problems going into the holes I center-punched. The head of the screw sinks flush with the surface of the L-bracket so you end up with a flat surface area. Overall a good shopping experience. Would come back again if needed.

**Q: How many of these would I need to brace the corners of a bed platform?**
A: I have no idea without seeing the platform. I will say that I made a table with 4x4" legs (4 legs) and put two braces per side of the 4x4s.  That's 8 braces per leg. I wanted the screws to bite in deeper, so I bought longer screws to anchor the braces. I'm able to sit on it and bounce around without the table shaking at all.

**Q: Can these be used on an aluminum extustion greenhouse?**
A: I'm sure the bracket would satisfy your needs, however I'm not a fastening expert, but your might consider replacing the fastening hardware / or verifying the provided screws will properly secure it to your aluminum structure.

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.
