    These are so important to have in your drawer.
    If your looking at this product then you probably have an issue with bolt and nuts of all kinds and sizes that don't match. Yup I have this same problem and slowly over time I try to match them up and keep them to the side so I will have a matching set. Its inevitable when your building something that you need the right bolt and nut and you don't have it. Especially when they are small parts! This is a great set. Its plenty of bolts and nuts with the M3 Hex key. They are plenty strong and well organized. I love having sets like this because it makes my life so much easier. Also its much much less than buying some bolts and nuts at the big box store. This cheap set is worth the price.

      I'm still so impressed! This is not even close to what I needed, its a way smaller scale than what I needed to work with a large exercise machine.

      1) This was very professionally packaged and included a thoughtful card from the seller
      2) The plastic case seems much more sturdy and well constructed than so many other cases I have seen
      3) The lid on the plastic case clearly describes the contents, which I think is useful and practical feature
      4) I will not return them because they may come in handy for the future

      Great hardware selection. I bought this for a couple of small projects, and was happy with the product. I didn't think I'd use the provided Allen wrench but it turned out to be handy. I'm surprised how many pieces I've used already, will need another set soon.

      I'm not going to rate down this SZHKM 500pcs M3 Nuts and Bolts Assortment Stainless Steel set because it was smaller than expected. Not the count, but the size of the pieces. That's because I didn't read the description as well as I should have. Anyway, they are as described. They also work as described. They are small and meant for small projects. Like to fix my purse where the rivets on the handles broke and I used the nuts and bolts from this set as replacements and now my purge is back in action.

      That alone made me very happy to have tried out this set. It also works well for another family member who does like making small robotic projects and such. The pieces are small that I wouldn't recommend it for a household with young children and babies. For older kids and teenagers, it is fine.

      I received the Saturday anxiously waiting to use them to replace a lot of hardware on my pool that has some non-stainless steel bolts holding the ladder. To my astonishment I did not realize that these are very small stainless steel screws fit more to repair or build models RC cars and very small Electronics. Aside from that it look great and function perfectly fine.
