### ⭐⭐⭐⭐ Good product but . . .

This is a review of the Wugongshan 1080 Pcs Screws Bolts and Nuts Assortment Kit, Metric Machine Screws and Nuts and Flat Washers, M3/M4/M5/M6 Cross Slotted Round Head Bolts Sets © I think most people buy fastener assortments, such as this, to have a solution at hand when unexpected situations arise. I have no issues with this product for this purpose. The quality of the parts seems fine. However, another reason people buy assortments like this is to have neatly compartmentalized parts for ready, efficient access as opposed to that old coffee can full of miscellaneous fasteners. Unfortunately, this arrived as a, still sealed, jumble, requiring thirty minutes of sorting to put parts into their correct respective cubby holes. Now this is not that unusual but normally it results from the jostling in shipping that causes some parts to overflow into adjacent sections. This was not quite the case here but that did happen. In some sections incorrect fasteners had not just overflowed the dividers, they were thouroughly mixed with other fasteners. If the top lid is flat, the pressure of that lid, against the dividers, cuts down on overflow and minimizes parts migration from compartment to adjacent compartment. Generosity, poor sorting or package engineering was the culprit in this case. There were many more M6 nuts and M3 x 20 mm screws than would fit into their designated compartments thus bowing the lid and putting them into other compartments. Many companies that provide these assortment boxes insert a thin layer of compressible foam to minimize part migration between sections. This product does not include one of these inserts. Overall, this is a good product at a good price. Just be prepared to do some sorting on arrival. Since these parts are not stainless steel a small pair of magnetized tweezers helps with that process.
