No more running to the hardware store

Having this kit at home saves me so much time. The organization is decent, and the door-to-door delivery was surprisingly fast. The washers fit the bolts perfectly.

Great value, good variety

Really happy with the assortment of M3 and M4 sizes. The flat head design sits flush perfectly. Only giving 4 stars because the plastic case latch felt a bit flimsy, but the screws themselves are top quality.

Perfect for home repairs

This kit has everything I needed for fixing loose cabinet handles and assembling a new shelf. The 304 stainless steel feels very durable and hasn't rusted despite being used in the kitchen.

Essential for electronics projects

I use these primarily for mounting components in my hobby electronics projects. The self-tapping feature works smoothly on plastic enclosures without cracking them. Highly recommended.

Excellent corrosion resistance

Used these for a bathroom fixture repair. After three months of exposure to humidity, there is zero sign of rust. The flat head design looks very clean and professional.

Solid basic kit

Good quality steel that doesn't strip easily. I've used about half the box for various furniture assemblies. Would be nice to have a few M5 options included, but for M3/M4 needs, this is excellent.

5 FAQ

Q: Does this kit include a screwdriver?

A: No, this kit contains only the fasteners (screws, nuts, bolts, switch screws, and washers). Tools are not included.

Q: Are these screws magnetic?

A: 304 stainless steel is generally non-magnetic or weakly magnetic. These screws may show slight magnetism due to the cold-heading manufacturing process, but they are not strongly magnetic like carbon steel.

Q: Is the storage box stackable?

A: The current design features a snap-shut lid for secure storage but does not have interlocking features for stacking multiple boxes vertically.

Q: Can I use these on wood?

A: Yes, the self-tapping design allows them to be used on wood, plastic, and thin metal sheets. For hard woods, we recommend pre-drilling a pilot hole to prevent splitting.

Q: What is the length range of the screws in this kit?

A: The kit includes a variety of lengths suitable for general home use, typically ranging from 6mm to 20mm for the M3 and M4 sizes included.
