Here’s a 10-piece pack of M12-1.75 flange lock nuts from Rivercity Fastener.

These are all-metal, so they’re designed to stay put even under vibration—no nylon insert here.

They meet DIN 6927 standards and are made from high-strength steel with a grade 10.9 rating.

The zinc plating gives them a clean finish and helps resist corrosion.

Perfect for automotive, machinery, or any heavy-duty application where a secure fit matters.

External hex drive makes them easy to install with standard tools.

Metric thread, 12mm x 1.75, and ready to go.
