Essential for electronics assembly

The ultra-thin flat head design is perfect for mounting components where space is tight. The cross drive grips the screwdriver nicely without stripping.

Good value, mostly accurate sizes

Great variety of sizes from M3 to M8. One compartment had a few mixed sizes, but overall the quality of the metal is solid and they fit well.

Solid kit with minor packaging issue

The screws and nuts are great quality. The plastic divider in the box cracked during shipping, but the hardware itself was undamaged and works perfectly.

High quality 304 steel

I used these for an outdoor project and they have shown no signs of rust after three months of exposure to rain. Highly recommended for durability.

5 FAQ

A: The box is designed with a flat lid and base, allowing it to be stacked securely with other standard hardware organizer boxes.
