Review: Handy Bolt Set with Minor Packaging Issue - I buy a lot of these assorted nut and bolt sets, and this M4 405-piece kit is pretty good overall. The bolts, nuts, and washers are well machined and consistent, which is exactly what you want for general workshop use or hobby projects. The included case is compact and clearly labelled, which makes it easy to find what you need quickly. The only slight issue was that a few of the plastic dividers had come loose during shipping, so some of the compartments had mixed contents when it arrived. It was easy enough to sort out, but worth knowing in case you are expecting it to be ready to use straight out of the box. Still, for the price and the quantity, it is a solid purchase and a useful addition to any toolkit.
