  • COMPLETE 5-IN-1 FULL REPAIR KIT: A massive 1440-piece fully mated collection providing an all-in-one hardware solution. Every single compartment features perfectly matched cylindrical socket head screws, hex nuts, flat washers, and spring lock washers, plus 3 corresponding Allen keys for instant setup.
  • DEEP HEX SOCKET CAP DRIVE: Precision-machined with standard metric coarse threads and clean internal hex drives that guarantee maximum tool engagement. The cylindrical socket cap design distributes high clamping force evenly while resisting head stripping or shearing under high torque.

  • Micro and Small bolt size
Size: M2 M3 M4 M5 860pcs 3
Good booty set for smaller to micro metric bolt size. Durable and a good value

  • Great for 3d printing
Size: M2 M3 M4 M5 860pcs 2
Great set of screws for 3d printing enthusiasts. only gripe would be that everything is sorted except one size of springs and bolts that are thrown together. But not a deal breaker at all.

  • Good Quality for Light Projects, Saves a Trip to the Store
Size: M2 M3 M4 M5 860pcs 2
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, it’s a very practical kit that saves time and hassle. That said, I did run into one issue: the included allen wrenches didn’t properly fit the M4 screws. For me, that wasn’t 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 what’s in the box. Because of this, I’d personally rate the product around 4 stars instead of 5. It’s 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, I’d 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, I’m pleased with the purchase and would buy this set again. It’s convenient, affordable, and takes the stress out of finding the right metric screw in the middle of a project. While it’s not perfect, it definitely does the job and makes for a handy addition to any toolbox. For the cost and the convenience, it’s tough to beat. ... show more

  • Awesome, strong, and durable, these were just what I needed.
Size: M2 M3 M4 M5 860pcs 2
The packaging is very nice, the screws, nuts, and washers are all well organized into little bins, and easy to find and grab. The various lengths are also quite nice. The screws are also quite durable and strong.

  • A great variety of screws
Size: SS M5 307pcs 3
A great variety of screws. Just let others know that the screws have weak magnetic property. I contacted the seller with the confirmation of 304 stainless steel. I guess the weak magnetic properties may be due to the manufacturing process. One thing that I didn’t pay attention to when I made the purchase is that the number of nuts (60) is less than the total bolts (84). So, some of the bolts would not be useful unless buying extra nuts somewhere else separately. I would recommend the seller to include matching number of bolts and nuts to make the full use of the kit. ... show more

  • The Right Fit for me Bike (Just Don’t Over-Torque) The Right Fit for me Bike (Just Don’t Over-Torque)
Size: M2 M3 M4 M5 860pcs 3
I needed some crews to attach accessories to my ebike, and this Screw Kit worked wonders! It introduced me to the world of metric fasteners. It’s a versatile set that has simplified my DIY projects. . [ What I like about it ] 1. Precision Engineering: Every piece is true to size. I double-checked the measurements, and the screws and components match the advertised specifications perfectly. 2. Well Organised: The kit is thoughtfully laid out with clearly labelled compartments. The sheer variety ensures I have the right part on hand for almost, if not, any small-scale repair. 3. Reliable Value: While the metal isn't industrial-grade, the quality is more than sufficient for its price point. For example, my reasons for buying it are securing bike components; the screws are sturdy, reliable, and get the job done. . [ My experience ] -- One time when I needed to fasten something very tightly using a knut and screw. Suddenly, the knut snapped off! So yeah, this kit may not be good for very tight screws. ... show more
