Perfect for 3D printer mods
Used the M3 and M4 sizes for hotend adjustments. No stripping on the hex sockets.

Great for machinery repair
Used these for securing pulleys on a conveyor belt. The flat end holds well without damaging the shaft.

Good quality, messy box
The screws themselves are top notch 304 steel. The compartment box was a bit cracked on arrival though.

Consistent threading
Checked a sample with thread gauges. Everything is within tolerance. Will order again.
