Solid Construction
These nuts are very sturdy and the black finish looks professional. The lock washers grip well without damaging the surface.

Exact Match
Fit my M12 bolts perfectly. The threading is clean and precise. Will order again for future projects.

Great Locking Feature
The claw washer works well to prevent loosening under vibration. Exactly what I needed for my equipment.

Good but Greasy
Quality is fine but they arrived a bit oily from the manufacturing process. Cleaned them up and they work great.
