Perfect for electrical box repairs

Exactly what I needed to secure some loose socket panels. The M4 size fit perfectly, and having the nuts and washers included saved me a trip to the hardware store.

Handy assortment

Great little set for general maintenance around the house. The round head sits flush enough for my switch plates, and the cross recess grips the screwdriver well.

Decent but basic

They work as expected for light duty tasks. The metal feels a bit thin compared to industrial grade, but for hanging a switch panel, it is sufficient.

Good value kit

The screws are decent quality for household use. The caps are a nice touch to cover the screw heads for a cleaner look. One nut was slightly stripped, but plenty of spares.

Solved my wobbly outlet issue

My kitchen outlets were loose because the original screws were stripped. These M4 screws tightened everything up securely. Very satisfied with the purchase.

5 FAQ

Q: Is a screwdriver included in the package?

A: No, this set includes only the screws, nuts, flat washers, and caps. You will need to provide your own Phillips head screwdriver for installation.

Q: Are these screws suitable for outdoor electrical boxes?

A: While they are zinc-plated, we recommend them primarily for indoor household use. For outdoor applications exposed to heavy rain, stainless steel screws would offer better long-term corrosion resistance.

Q: What is the length of the screws in this set?

A: This specific household set typically contains M4 screws with a length of 10mm, which is standard for most switch panels and socket faceplates.

Q: Do the caps snap on or screw on?

A: The included caps are designed to snap securely over the round head of the screw after installation to provide a smooth, finished appearance.

Q: Can I use these to mount a heavy light fixture?

A: These screws are intended for securing faceplates, switch panels, and socket covers. They are not rated for supporting the weight of heavy light fixtures; please use appropriate mounting hardware for those installations.
