M8-1.25×80mm 六角穴付きボルト | クラス10.9 鋼 無処理 | 全ねじ (100本/パック)

The threading is clean and consistent on every single bolt, so they spin on smoothly without any binding. Used a full bag on a repair job and didn't have to chase a single thread. For 10.9 grade at this price, the box is a solid deal.

I've been through a lot of hex bolts over the years, and these fully threaded ones are a step above what I usually grab. The 10.9 grade steel feels properly hardened, and the hex heads fit a socket wrench snugly with zero rounding off. They're a solid pick for heavy equipment assembly.

The threads are clean and uniform along the entire 80mm length, so they seated smoothly into pre-tapped holes without any binding. Class 10.9 is the real deal for heavy equipment; these held firm when I torqued them down on the frame.
