Essential for electricians

I keep a pack of these in my van. They fit standard 86-type panels perfectly without stripping easily.

Solid construction

Very sturdy steel. I used the 6cm size for most of my outlets and they hold tight.

Solved my renovation issue

Renovating an older home required longer screws than usual. These M4 extended screws worked flawlessly.

Perfect for deep boxes

Finally found screws long enough for my extended junction boxes. The 8cm option was a lifesaver for a thick wall installation.

Good quality, great variety

The zinc plating looks durable and the cross recess is well-defined. Only wish the kit came with a small storage case.

Great value pack

Having multiple lengths in one purchase saved me several trips to the hardware store. Highly recommended.

5 FAQ

Q: What screwdriver size do I need for these?

A: A standard PH2 (Phillips #2) screwdriver is recommended for optimal torque and to prevent stripping.

Q: Is the zinc plating suitable for outdoor use?

A: While zinc plated offers good corrosion resistance, we recommend stainless steel variants for direct outdoor exposure or high-humidity areas.

Q: Can I buy just the 8cm length separately?

A: Currently, we only offer the assorted kit with mixed lengths. Please check our bulk section for single-length options in the future.

Q: Do these fit European standard sockets?

A: These are specifically sized for 86-type junction boxes common in many regions. Please verify your box dimensions before purchasing for European standards.

Q: Are these screws compatible with plastic junction boxes?

A: Yes, these M4 screws are universally designed for both metal and plastic 86-type junction boxes.
