Perfect for electronics projects

The M2 and M3 sizes fit my 3D printer frame perfectly. The black finish looks professional.

Strong and durable

Used them on a bike rack assembly. They are holding up well against the elements.

Good quality fasteners

Most nuts were great, though one size felt slightly tight. Overall good value for the price.
