Well-Organized and High Quality
15000 pcs – They were not kidding – I have enough Screws, Nuts and washers for a lifetime. This set is perfect for small projects, 3D printer maintenance, and furniture repairs. The screws and nuts are solid and well-machined, with consistent threads and a durable black finish. I like that it includes a wide range of sizes (M2 to M6) and five matching Allen wrenches. Everything came neatly organized in a compartmentalized case, which makes it easy to find what I need quickly. Great value for anyone who regularly works with metric hardware.

Great assortment for a fantastic price
I initially only needed a couple of screws for a very specific use case (additional mount of something on my 3D printer), but have since used these in a number of places. They are high quality, and work flawlessly with both the included nuts and existing threaded holes. The variety is exactly what I needed, whether I knew I needed them all or not, and the multiple lengths has come in handy. Would definitely buy again and strongly recommend.

secured exterior lamp
Review April 2025 for LuKaiSen 1500 pcs Screws Nuts & Washers. Was able to find the right size to secure the top of an exterior lamp. This kit provides better size variety than most, since it provides materials for 5 different sizes: M2, M3,M4,M5 & M6 in 3 different lengths. The exterior plastic container is sturdy and closes securely. All the items in each compartment are secured inside small re-closable plastic bags, which is organized and appreciated. The screws have a light coating of oil. The included Allen Wrenches make it easy to install and remove the screws. A good choice if you don’t know what size you need. It is described as being suitable for outdoor conditions.

Good Quality for Light Projects, Saves a Trip to the Store
I picked up this metric screw set for a small project I was working on, and overall, it was exactly what I needed. Having a variety of sizes in one organized case made it much easier than running to the hardware store and trying to find the right screws on the spot. The assortment covers a good range, and I appreciated having everything on hand when I needed it. For the price, itâs a very practical kit that saves time and hassle.That said, I did run into one issue: the included allen wrenches didnât properly fit the M4 screws. For me, that wasnât a dealbreaker since I already had my own set of wrenches, but I could see how that might frustrate someone who was relying only on whatâs in the box. Because of this, Iâd personally rate the product around 4 stars instead of 5. Itâs a minor flaw, but still worth pointing out for anyone considering the set.The quality of the screws themselves seems decent for light to moderate use. They held up well for my project and threaded in cleanly without any problems. If I were working on a motorized project or something requiring a higher-grade steel, Iâd probably invest in a more heavy-duty set. But for everyday fixes, DIY builds, or quick repairs, these screws are more than sufficient.In the end, Iâm pleased with the purchase and would buy this set again. Itâs convenient, affordable, and takes the stress out of finding the right metric screw in the middle of a project. While itâs not perfect, it definitely does the job and makes for a handy addition to any toolbox. For the cost and the convenience, itâs tough to beat.
