Excellent quality and organization

This kit is exactly what I needed for my workshop. The 304 stainless steel feels very durable, and the plastic box keeps all the different sizes neatly separated. The combination head makes it easy to use either a Phillips or flathead screwdriver.

Good set, missing a few M6 nuts

Overall a fantastic set. The screws and washers are top quality. I noticed my specific box was short two M6 nuts, but given the low price and the sheer volume of other parts, it's still a great deal. Customer service was responsive.

Great value for money

I bought this for assembling some outdoor garden furniture. Since it's 304 stainless, I'm not worried about rust. The variety of sizes from M2 to M10 covers almost every project I have coming up. Highly recommended.

Fast delivery and well packed

Arrived earlier than expected. The packaging prevented any mixing of sizes during transit. The metal quality is genuine 304 steel as described; I tested it with a magnet and it showed the expected slight attraction typical of worked stainless.

Solid hardware kit

Very useful assortment. The only reason I didn't give 5 stars is that the latch on the plastic box feels a bit flimsy, but the contents themselves are excellent quality. Will definitely buy again when I run out.

Perfect for electronics projects

As an hobbyist working with small electronics, having the M2 and M3 sizes in this kit is a lifesaver. The springs washers provide good tension, and the finish is clean and professional looking.

5 FAQ

Q: Can I purchase refills for just the M3 size?

A: Currently, we only sell the complete assortment kit. Individual size refills are not available at this time, but many customers find the full kit provides enough spares for long-term use.

Q: Are these screws suitable for outdoor marine environments?

A: While 304 stainless steel offers excellent corrosion resistance for most outdoor applications, for constant exposure to saltwater or harsh marine environments, we recommend 316 stainless steel for maximum longevity.

Q: Does the kit come with a drill bit or driver?

A: No, this kit contains only the fasteners (screws, bolts, nuts, and washers). Tools such as screwdrivers or drill bits are not included.

Q: Is the box stackable if I buy multiple sets?

A: Yes, the plastic case is designed with a uniform footprint, allowing you to stack multiple boxes securely on top of one another for organized storage.

Q: What is the thread pitch for the M4 screws?

A: The M4 screws in this set feature a standard metric coarse thread pitch of 0.7mm.
