M12-1.75 X 55mm 六角ボルト | クラス10.9鋼 黄亜鉛メッキ | 全ねじ (325本/袋)

Stripped a few cheaper bolts in my last project, but these hold torque without any give. Class 10.9 steel with the yellow zinc finish makes them feel seriously tough, and the full threading is a lifesaver when you need a tight grip at odd angles.

The yellow zinc coating on these M12 bolts is holding up perfectly in my damp workshop, even after a few months. They thread cleanly into existing tapped holes without any binding. Exactly what I needed for heavy equipment assembly.

I needed a full box of these for a machine rebuild, and the yellow zinc coating on every single bolt looks uniform and clean. The hex heads seated nicely in my socket without any stripping, and the threads were burr-free right out of the package.
