Great value bulk pack

Bought these for a large wiring project. The count was accurate, and the consistent quality made the installation much faster.

Good quality, sharp points

Very sharp and easy to drive. The black finish looks professional. One screw had a slightly uneven head, but the rest were perfect.

Solid choice for electronics

Works well for securing components in electrical boxes. The countersunk head sits flush as expected. Would prefer a Phillips #2 drive instead of #1.

Excellent hardness

I've used cheaper screws that snap when tightening into hard plastic enclosures. These hardened screws held up perfectly with no breakage.

Perfect for control panels

These screws are exactly what I needed for mounting industrial switches. The self-tapping feature works smoothly on thin metal panels without stripping.

Reliable and sturdy

No issues with threading or rust so far. They grip tightly and hold the switches securely in place even under vibration.

5 FAQ

Q: What is the total length of the screw?

A: This specific listing offers lengths ranging from 10mm to 25mm. Please select your required length from the dropdown menu before adding to cart.

Q: Can I use a power drill to install these?

A: Absolutely. A cordless drill with a Phillips bit set to a low torque setting is recommended to avoid over-driving the countersunk head.

Q: Are these screws suitable for stainless steel panels?

A: While they can penetrate thin stainless steel, we recommend pre-drilling a pilot hole for best results to prevent bit wear and ensure a clean thread.

Q: Do these come with matching nuts?

A: No, these are self-tapping screws designed to create their own threads in the material and do not require nuts for installation.

Q: Is the black coating corrosion resistant?

A: Yes, the black zinc plating provides moderate corrosion resistance suitable for indoor electrical applications. For outdoor use, consider our stainless steel variants.
