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

Q: Can I buy refills for just the M4 screws if I run out?

A: The M6 screws in this combination kit feature a standard coarse thread pitch of 1.0mm.

Q: Does this kit include both metric nuts and washers for every screw size?

A: Yes, the kit includes matching 304 stainless steel nuts and flat washers for all screw sizes ranging from M3 to M8.

Q: Is the storage box stackable with other similar kits?

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