Review on 1/4" Thick Heavy Duty Shelf Brackets, 6.25"X4.25", 4 Pack - Up To 66Lb, Metal Rustic Farmhouse Cottage Wooden Floating Shelves Brackets, Industrial Wall Corner Mount, With Screws And Wall Anchors by Mark Morrow

Bracket measurements are accurate for LxWxH, though some are maybe 1-3° off from 90°. Most of the edges are chamfered, so there aren’t really any sharp/pointy bits. Powder coating seems even and adequately applied.Screws are slightly shorter than the published lengths by 1-3mm, but not a big issue. When completely flush, the screws extend roughly 3cm/1.25” and 12mm/0.5” respectively.Each bracket is individually bubble wrapped, so minimal chance for shipping damage.One small suggestion for the manufacturer/seller is to note down on the box what size drill bit to use. 8mm is listed here on the product page, but that means having to come back here to check vs. just looking at the box.
