Perfect for chassis work
I use these for securing electronics chassis. The M3 and M4 sizes are very consistent.

Good quality, heavy package
The nuts are good quality for the price. Just be aware the box is very heavy when it arrives.

Solid hardware
Grade 4.8 is standard for general use. Would recommend for non-critical structural applications.

Great bulk value
Exactly what I needed for my workshop. The zinc plating looks solid and the threads are clean.
