Solid hardware

Nice assortment of sizes. The mushroom head provides a good bearing surface. Only giving 4 stars because the packaging was a bit crushed upon arrival, but the screws themselves are fine.

Sturdy and reliable

Used these for an outdoor garden box project. Since they are 304 stainless steel, I am confident they will withstand the elements without corroding. Highly recommended.

Professional grade fasteners

I use these in my small electronics repair shop. The self-tapping feature works smoothly on aluminum chassis, and the black color matches our aesthetic perfectly.

Great value for money

Bought these for assembling furniture where silver screws looked out of place. The black zinc plating is uniform and professional looking. Will buy again.

Perfect for my DIY projects

These screws are exactly what I needed. The black finish looks sleek on my custom PC case, and the stainless steel ensures they won't rust over time. Very happy with the purchase.

Good quality, slightly tight fit

The build quality is excellent and the heads don't strip easily. They were a bit tight going into hard plastic, but that also means they hold very securely once installed.

5 FAQ

Q: Can I use these for outdoor fencing?

A: Yes, 304 Stainless Steel offers good corrosion resistance for most outdoor environments. However, for coastal areas with high salt exposure, 316 Stainless Steel would be a more durable choice.

Q: What length options are available for the M4 size?

A: The M4 size in this specific kit comes in lengths ranging from 10mm to 30mm. If you need specific longer lengths, please check our bulk listing for individual sizes.

Q: Does the black coating chip easily?

A: The black zinc plating is durable for standard assembly. However, excessive force or using the wrong screwdriver size can cause chipping. We recommend using a properly sized Phillips head driver.

Q: Is a drill bit included in the package?

A: No, this package contains only the screws. Since they are self-tapping, they can often create their own threads in soft materials, but a pilot hole is recommended for harder metals or dense woods.

Q: Are these screws magnetic?

A: 304 Stainless Steel is generally non-magnetic or weakly magnetic. These screws may show slight magnetism due to the cold working during manufacturing, but they are not strongly magnetic like carbon steel.
