Essential for electronics projects

I use these primarily for assembling custom PC cases and mounting components. The M3 and M4 sizes are exactly what I needed, and the spring washers provide excellent tension.

Good quality, slightly small box

The screws and nuts are high quality and fit perfectly together. My only minor complaint is that the plastic organizer box is a bit tight when closing it with all compartments full.

Solid hardware set

The threads are clean and cut well. I stripped one screw due to my own error, but the rest have held up great under torque. Would buy again.

Neatly organized and complete

Love the compartmentalized box. It makes finding the right size incredibly easy. The combination of flat and spring washers is a nice touch that many other sets miss.

Great value for money

I was surprised by how many pieces were included for the price. Having the matching washers and nuts saved me a trip to the hardware store. Highly recommended for DIY enthusiasts.

Perfect assortment for my workshop

This kit has everything I needed for various repairs around the house. The 304 stainless steel feels very durable and hasn't shown any signs of rust after a few months of use in the garage.

5 FAQ

Q: Can I purchase refills for just the M5 nuts if I run out?

A: Currently, we only sell the complete combination sets. Individual component refills are not available at this time.

Q: Are these screws suitable for outdoor marine environments?

A: While 304 stainless steel offers good corrosion resistance, for constant exposure to saltwater, we recommend 316 stainless steel for better protection against rust.

Q: Does this set include an Allen key or screwdriver?

A: No, this set includes only the screws, nuts, flat washers, and spring washers. Tools are not included.

Q: What is the length range of the screws included in the M4 size?

A: The M4 screws in this assortment typically range from 6mm to 20mm in length, covering most standard application needs.

Q: Is the box stackable with other similar kits?

A: The box does not have interlocking stacking features, but its rectangular shape allows it to sit securely on top of other standard storage containers.
