Good but dusty

Quality of the steel is excellent. Arrived with some industrial oil residue, but that is expected.

Bulk value

Needed many M5 screws for a project. This pack was perfect and saved me multiple trips to the store.

Solid Hardware

Used these for assembling a heavy-duty workbench. The 10.9 grade holds up well under tension.

Great for automotive

Used M6 size for an engine cover bracket. High strength gives me peace of mind for vibration.
