Essential for professional electricians

I keep a box of these in my van at all times. The variety of lengths in the pack saves me from running to the hardware store mid-job. True 304 steel as advertised.

Good screws, packaging could be better

The screws themselves are excellent quality. However, the plastic organizer box arrived with a cracked lid. The screws didn't fall out, but better packaging would be nice.

No rust after 6 months

Installed these in my garage where it gets quite damp. Six months later and there is zero sign of corrosion. The round head sits flush perfectly on the Type 86 panels.

Exactly as described

Fast shipping and the product matches the description perfectly. The countersunk head allows for a very clean finish on the switch plates. Highly recommended for DIYers.

Perfect fit for thick walls

Finally found screws long enough for my renovation project. The extended length up to 7cm was exactly what I needed for the deep junction boxes. The stainless steel quality feels premium.

Good quality, slightly pricey

These M4 screws are very sturdy and the cross head doesn't strip easily. They are a bit more expensive than standard zinc screws, but the rust resistance is worth it for bathroom installations.

5 FAQ

Q: Does the kit include a screwdriver bit?

A: No, this package contains only the screws and the storage case. A Phillips #2 bit is recommended for installation.

Q: Are these screws compatible with standard US outlet boxes?

A: These are designed specifically for Type 86 panels, which are common in Asia and Europe. They may not fit standard US electrical boxes without adapters due to thread pitch differences.

Q: Is the 70mm length available individually if I need more?

A: Currently, we only sell the assorted kit. Individual lengths are not available for separate purchase at this time.

Q: What is the exact thread pitch for the M4 screws?

A: The thread pitch is standard 0.7mm for M4 metric screws, ensuring compatibility with most metric threaded inserts in switch sockets.

Q: Can I use these outdoors for security camera mounting?

A: Yes, since they are made of 304 Stainless Steel, they offer high corrosion resistance suitable for outdoor use, provided the mounting surface is also weather-resistant.
