582 Pieces Large Metric Nut Assortment Set,M2 M2.5 M3 M4 M5 M6 M8 M10 M12 Nylon Insert Hex Lock Nuts Kit 304 Stainless Steel and Black Carbon Steel Nylon Inserted Self Locking Nuts for Screws Bolts

At 582 pieces, this is a pretty complete set of Metric Locknuts. The sizes range from M3 to M12. To see the sizes in perspective, look at the photos with the penny next to the nuts.The come in 304 Stainless Steel and Black Carbon Steel. These are very strong metals and are able to be used outside.The rubberized part of the locknut seems to be secured tightly and will form a great lock when tightened.I really appreciate that the dividers inside the plastic box are not movable or interchangeable. They are fixed in one place. If the spacers were movable and could slide out, it would really be a mess sorting out the locknuts when the little ones slip underneath to another space.I also like when a picture of the product is glued to the outside of the lid, and on the inside when the lid is open. This way I know what box to reach for when I need them, and when I open the box, I know which space they are all in. It makes it so easy to find what I want. This box is a bit different. There is one piece of loose paper on the inside of the box. The box is see through, so the paper shows through the lid to identify what's in the box. When I opened the lid, I realized that the sizing and placement paper was just sitting on top of the nuts. The paper has to be flipped over in order to see the size and placement of each piece. The paper looks as if it was cut with a pair of scissors, as the the borders are not all even. None of this affects the quality of the the nuts themselves, but I've never seen a piece of paper just laying in the box like this before and needing to be flipped to use it.Now to the box itself. I really like it. As mentioned, the spacers are not movable. The box feels pretty sturdy and the closing latches appear to hold the box tightly closed.All said and done, this is a very nice set. If there was a 4 1/2 Star choice, I would select that. But, as in baseball, tie goes to the runner, so 5 Stars it is.
