Solid hardware

Very reliable fasteners. The flat washers distribute load evenly. Using them for structural supports in our facility and they perform as expected.

Good variety, sturdy build

The assortment covers most of the sizes we need for general repairs. The spring washers are particularly high quality. Only wish it included a few more M8 bolts.
