These brackets are well worth the money! I was looking at similar brackets at a big box, brick and mortar store for a kitchen shelving project. These were similar but cheaper. The difference being that they didn’t hold as much weight. This wasn’t a concern for me as I was attaching to furring strips instead of studs, which were not centered so I had to use more brackets than necessary to give it a more centered appearance. At 75# per bracket weight will never be an issue. These also came with their own screws and anchors which the other store did not. I was not able to use them for my project, again because of the outside walls being block with furring strips, there wasn’t enough air space between the drywall and the block to accommodate the length of the anchors and screws, but this is another economical addition to buying these brackets. I would definitely recommend. Good quality, durability, style and function.

I needed to mount a heavy wood shelf and wanted something with clean lines that would keep it safely in place above a bed. These are heavy duty solid iron and I mounted them into wall studs. Instructions didn't say what size drill bit to use, but 9/64" worked perfectly. The package has drywall mounts too, but I can't imagine they'd hold safely. Put the shelf up and it looks great! The lip on the front of each bracket is another plus that keeps the shelf from slipping forward.
