I recently purchased the DYWISHKEY 200-piece set of M3 stainless steel hex screws, and I am thoroughly impressed with their quality. This kit, featuring screws in lengths of 30mm, 35mm, 40mm, 45mm, and 50mm, is exceptionally well-crafted. The precision and quality of these screws are evident right out of the box. Each piece is uniform in size and finish, which speaks volumes about the care and quality control put into this product. The stainless steel 304 material is durable and gives me confidence in the longevity and strength of these fasteners. What I appreciate most about this kit is its versatility. The variety of lengths makes it suitable for a wide range of applications, and I found it perfect for multiple projects, including some involving intricate assembly. In summary, the DYWISHKEY 200-piece stainless steel hex screw kit is a fantastic find. Its high-quality craftsmanship, combined with the variety of sizes, makes it an essential kit for anyone needing reliable and well-made fasteners. Highly recommended for both professional and DIY use.

Fine quality and works well. Came in handy for a few 3d printing projects.

This set comes in a nice secure reusable case. The screws are high quality and well packaged with each size having its own compartment and a detailed location list. I have a Voron 2.4 R2 3D printer I built from a Formbot kit and I needed extra long M3 bolts for some of my modifications. This set is just what I needed to complete them. If you are like me and into 3D printer building, you will find a lot of uses for these extra long screw set. Well made and well worth a full 5 stars.

I needed these for a model project I was working on. They are manufactured well work very good.

Good value; comes in handy on small projects

This kit is a great deal for all the different screws you get - I would definitely have paid much more piecing this together at my local hardware store. Additionally, they don't arrive covered in gear oil! So far, I've yet to strip any of these out, so the durability of the threads and caps are great for projects that need a little extra holding torque. When I need to restock, I'll definitely be buying again.

I keep these and many other sizes on hand for different projects I take on either machining on my lathe and mill or 3D printing. They have been good enough for my needs, though I use hardened hardware whenever something is going to see stress that may cause failure. Very few issues with threads being bad after several boxes. Average is probably less than one per box.

The pictures make the scale size look iffy but they are exactly what they say they are. They're durable and true with no imperfections.
