M12-1.5×25mm 六角ボルト | クラス10.9 鋼 無処理 | 全ねじ (500本/袋)

Half a thousand of these in one box and every single one is fully threaded, which saved me a trip to the hardware store mid-project. The Class 10.9 steel feels dense and solid in the hand, and the hex head grips cleanly with a socket. Exactly what I needed for heavy machinery assembly.

These hex bolts fit my jig fixture perfectly; the 10.9 grade gives me confidence they won't strip under heavy torque. The fully threaded shafts let me adjust clamping depth exactly.

The threads are clean and uniform across every bolt in the pack, and the 10.9 steel feels properly hard when I torque them down. I grabbed these for a machine frame rebuild and they seated perfectly without any binding.
