Good value assortment

Great little kit for general home use. The screws are sturdy and the heads don't strip easily. I deducted one star only because I wished there were a few more of the longer cap screws included, but overall very satisfied.

Exactly as described

Needed specific M4 cap screws for a custom switch panel project. This set had exactly what I was looking for along with the necessary hardware to complete the installation. Fast shipping too!

Handy to have in the toolbox

As someone who does occasional DIY projects, having a pre-sorted set like this is a lifesaver. The round head design looks neat on visible fixtures. Everything fits together perfectly.

Perfect for electrical box installations

I bought this set to secure some new switch panels in my garage. The M4 size was exactly what I needed, and the inclusion of both nuts and washers saved me a trip to the hardware store. The zinc finish looks clean and professional.

High quality threads

The threading on these M4 screws is precise. They went into my socket mounts smoothly without any cross-threading issues. The flat washers distribute pressure well, preventing damage to the plastic housing.

Solid basic hardware

These are standard, reliable screws. Nothing fancy, but they do the job well for mounting light fixtures and outlet covers. The packaging kept everything organized until I was ready to use them.

5 FAQ

Q: Do the nuts fit tightly or do they require a lock washer?

A: The hex nuts are standard M4 size and provide a secure fit. While they hold well on their own, using a lock washer (sold separately) is recommended for applications subject to vibration.

Q: Are these screws suitable for outdoor use?

A: These screws feature a zinc plating which offers moderate corrosion resistance, but they are primarily designed for indoor home use such as switch panels and sockets. For prolonged outdoor exposure, we recommend stainless steel alternatives.

Q: What lengths of screws are included in this set?

A: The set includes an assortment of common M4 lengths ranging from 10mm to 25mm, suitable for most standard electrical box and panel applications.

Q: Is the material magnetic?

A: Yes, since these screws are made of carbon steel with zinc plating, they are magnetic. This can be helpful when working in tight spaces where dropping a screw might be an issue.

Q: Can I use a standard Phillips screwdriver with these?

A: Yes, these screws are designed for a standard Phillips #2 screwdriver, which is the most common size found in household toolkits.
