NOVWANG 500 pcs Aluminum Pop Rivets with Backup Washers Assortment Kit, 6-Values Size Blind Rivets Set with Labeled Case（1/8" x 1/4",3/8"; 3/16" x 1/2",5/8"; 1/4" x 1/2",5/8" ）

Good range of sizes. Nice storage box. Good number of rivets for each size.

This pop rivet assortment includes more than enough rivets in common sizes, however 1/4” rivets may be too large for some smaller rivet guns. The kit contains a total of 500 pieces to include washers, which is a very good deal. The case is convenient and arrived intact. All included items appear to be good quality.Although this is a very nice assortment and well worth the price, I cannot give it five stars for two reasons. The first reason as I already mentioned is that 1/4” rivets are starting to get on the larger-side and not everyone will be able to use them. The second reason is that the description describes these as “All aluminum pop rivet,” and this would be a huge advantage for certain applications such as marine or other outdoor use due to aluminum being rustproof. The only issue is that it does not specifically mention what material the mandrels are made out of as the most common material is stainless steel. There is a mention of “aluminum steel,” but what exactly is that? Additionally, are the washers constructed from stainless steel? These are all very important questions to ask depending on the intended application. To me, the mandrel feels like stainless steel, but I could be wrong. So, I would likely only use these for “indoor” projects.As far as what you are getting, when considering both the quantity and quality, it’s a very fair deal. These would be great for anyone who could use 1/4” blind rivets. If you do need to use these for “outdoor” projects, I would strongly recommend checking with the manufacturer first to find out exactly what metals are used for each application. All said, this is a very nice kit to have around, so yes, I would ultimately recommend it.
