High quality stainless steel

I've been using these for outdoor garden light repairs. No rust after three months of exposure to rain. Highly recommend for durability.

Good value set

Great assortment of nuts and washers. The only reason I didn't give 5 stars is that the box was slightly dented on arrival, but the contents were fine.

Solid hardware

The threads are clean and the heads don't strip easily. Good selection for general maintenance tasks around the house.

Great organizer box

The compartments in the box make it easy to sort the different sizes. The black coating seems durable and hasn't chipped off yet.

Exactly what I needed

Hard to find M2.5 black screws locally. This kit saved me a trip to the hardware store and had everything in one place.

Perfect for my electronics project

The black finish looks sleek and the sizing is accurate. I used the M2 screws for a Raspberry Pi case and they fit perfectly without stripping.

5 FAQ

Q: Can these be used outdoors?

A: Yes, 304 stainless steel offers excellent corrosion resistance and is suitable for most outdoor applications. However, in highly saline environments like direct ocean spray, 316 grade might be preferred.

Q: Is a screwdriver included in the set?

A: No, this set contains only the screws, nuts, and flat washers. You will need to provide your own Phillips head screwdriver appropriate for M2 and M2.5 sizes.

Q: Are these screws magnetic?

A: 304 stainless steel is generally non-magnetic or very weakly magnetic. These specific black-coated screws may show slight magnetism due to the manufacturing process but are not strongly attracted to magnets.

Q: Does the black coating wear off easily?

A: The black oxide finish is durable for standard use. Excessive friction during installation or contact with harsh chemicals may cause some wear over time, but it holds up well under normal conditions.

Q: What is the length of the M2 screws included?

A: This set includes a variety of lengths for both M2 and M2.5 sizes, typically ranging from 4mm to 12mm. Please check the detailed inventory list in the product images for exact counts per length.
