12''Folding Shelf Brackets Heavy Duty Max Load: 440b Stainless Steel Folding Bracket Workbench Brackets Desk Bracket Folding Down Table Wall Mounted for Work Bench, Space Saving DIY Bracket, 2 Pcs

I bought these to put a drop down table on the rear door of my camper van. It works very well for this application. The price is reasonable, and the brackets appear well made and sturdy, though I don't think I'd put 450 pounds on them. They come with flat head screws. I think pan head would be better since the bracket holes for them are not countersunk. I gave 4 stars instead of 5 because the edges of the stainless brackets felt a bit sharp. A few minutes with some fine sandpaper smoothed them over. Overall, for the price, these are great. I would buy them again if I needed more.

These are best for light duty use. It is a shame that these sellers are misleading consumers and in many ways selling a dangerous product for failure under damaging weights. In the picture it show a much heavy duty that was obtain from another seller. You can see the angle arm how much wider and stiff it is compare to the one bought from Amazon. The bottom bracket it is much heavier and beefed up all around.
