Solid basic kit

Does exactly what it says. The metal is genuine stainless steel, not the cheap plated stuff. The flat washers are uniform in thickness. Good addition to my toolbox.

Saved me a trip to the hardware store

I was missing just one specific M4 screw for my computer case fan, but this whole kit was cheaper than buying a single pack at the local store. Now I have spares for future repairs. Highly recommended.

Perfect assortment for home projects

This kit has everything I needed to fix my loose cabinet handles and assemble a new shelf. The M4 size is very common, and the inclusion of both round head and socket screws is a nice touch. The box keeps them organized perfectly.

Great for electronics hobbyists

Used these for mounting components in a custom switch panel build. The socket screws provided a clean, flush look while the round heads worked great for general fastening. Very satisfied with the purchase.

Excellent organization

The compartments in the box are well-sized so the washers and nuts don't mix together. The cross-head screws drive smoothly without stripping. A must-have for any DIY enthusiast.

Good quality, great value

The stainless steel feels sturdy and doesn't look like it will rust easily. I used the switch panel caps for a custom electronics project and they fit snugly. Only giving 4 stars because I wished there were a few more nuts included.

5 FAQ

Q: Are these screws magnetic?

A: Since they are made of 304 Stainless Steel, they are generally non-magnetic or only very weakly magnetic, which is normal for this grade of steel.

Q: Is the plastic box durable?

A: The organizer box is made from high-impact ABS plastic designed to withstand regular opening and closing without cracking under normal use.

Q: What is the length of the screws included?

A: This kit contains an assortment of lengths ranging from 6mm to 20mm to cover various home repair needs. Please refer to the internal label of the box for the exact count per size.

Q: Can these be used outdoors?

A: Yes, the 304 Stainless Steel construction offers high corrosion resistance, making them suitable for outdoor applications, although extreme marine environments may require 316 grade.

Q: Does the kit include an Allen key?

A: No, this kit includes the fasteners and storage box only. You will need to use your own standard M4 hex Allen key for the socket cap screws.
