墊圈，M8 14 mm外徑，0.5 mm厚

The 14 mm outer diameter fits my M8 bolt perfectly without any play, and at 0.5 mm thick it's just the right shim for dialing in alignment on my bench setup. Surfaced finish is clean and uniform, no burrs to worry about.

The low profile design is perfect for tight bench setups where every millimeter counts. It fits snugly without adding bulk, and the steel feels solid under torque.

The 0.5 mm thickness is exactly what I needed for fine-tuning the gap on my drill press table, and the 14 mm OD fits snugly without any wobble. Machined edges are clean, no burrs to speak of — these will definitely be my go-to shim washers from now on.
