Excellent variety for my workshop

This kit has everything I needed for various repairs around the house. The 304 stainless steel feels very durable and hasn't shown any signs of rust after being used on an outdoor gate.

Great for general maintenance

Used these to replace some corroded bolts on my bike rack. They installed easily and look much better than the old ones. Deducting one star because the M10 count was lower than expected.

Reliable stainless steel

I work in a humid environment and needed non-corrosive hardware. These have held up perfectly for three months now. Highly recommend for anyone needing reliable metric fasteners.

Sturdy storage box

Not only are the fasteners high quality, but the plastic organizer box is actually sturdy enough to keep in a toolbox without cracking. Keeps everything sorted by size.

Perfect fit and finish

Threads are clean and cut precisely. The round heads look professional on my custom furniture builds. The included washers fit perfectly every time.

Good quality, wish it had more M3

The quality of the screws and nuts is top-notch. My only complaint is that the box runs out of the smaller M3 sizes quickly if you are doing electronics work. Otherwise, great value.

5 FAQ

Q: Are these screws suitable for marine environments?

A: While 304 stainless steel offers good corrosion resistance, 316 grade is typically recommended for direct saltwater exposure. These are great for general outdoor use but may not be ideal for constant submersion in seawater.

Q: Is the box stackable with other kits?

A: Yes, the organizer box is designed with interlocking ridges on the lid and base, allowing it to stack securely with identical units.

Q: Can I buy refills for just the M4 size?

A: Currently, we only sell the full assortment kit. Individual size refills are not available at this time.

Q: What is the thread pitch for the M6 bolts?

A: The M6 bolts in this kit feature a standard coarse thread pitch of 1.0mm.

Q: Does this kit include hex keys or drivers?

A: No, this assortment kit includes only the screws, nuts, and flat washers. Tools are not included.
