Perfect assortment for my workshop

This kit has everything I needed for various small projects. The separation box makes it easy to find the right size quickly. The steel quality feels solid and durable.

Exactly as described

Fast shipping and the product matches the description perfectly. Having M3 through M6 in one kit saves me from buying multiple packs separately.

Good value, minor packaging issue

The screws and nuts are excellent quality 304 stainless. One divider in the plastic box was slightly cracked upon arrival, but the hardware itself is perfect.

Great for electronics projects

I use these primarily for mounting components in custom PC builds. The round heads look clean, and the Phillips drive grips well without stripping.

Solid hardware set

Very useful combination set. The washers fit snugly. I deducted one star only because I wished there were slightly more M4 screws compared to the others.

High quality stainless

Used these for an outdoor garden fixture. After a few weeks of rain, there is absolutely no sign of rust. Highly recommend for outdoor applications.

5 FAQ

Q: Does this kit include hex nuts or square nuts?

A: This kit includes standard hexagonal nuts compatible with the M3, M4, M5, and M6 screws.

Q: Is the storage box stackable?

A: The box is designed with a secure snap-fit lid but does not have specific stacking interlocks. However, its flat shape allows them to be stacked neatly on a shelf.

Q: What is the thread pitch for the M5 screws?

A: The M5 screws in this kit feature a standard metric coarse thread pitch of 0.8mm.

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

A: Currently, we only sell the complete combination set. Individual size refills are not available at this time.

Q: Are these screws suitable for use in marine environments?

A: While 304 Stainless Steel offers good corrosion resistance, 316 Stainless Steel is generally recommended for direct saltwater marine environments. These are great for general outdoor use.
