M6-1 x 18mm 六角穴付きボルト | クラス10.9 鋼 亜鉛メッキ | 全ねじ (400本/パック)

Needed some heavy-duty fasteners for a steel bracket repair on my milling machine—these class 10.9 bolts handled the torque without stripping. The fully threaded design made alignment a breeze with a deep socket.

Bought these for a jig I’m building and the hex heads seated perfectly in my socket driver without any stripping. The 10.9 steel feels noticeably tougher than the usual hardware-store stuff, and the zinc coating has held up fine so far. A full box of 400 means I’ve got plenty left over for other pro

These arrived neatly packed and the zinc plating looks even and clean across all 400 pieces. The class 10.9 hardness is obvious when you drive them in—no stripping or flexing, even with a ratchet. Exactly what I needed for a batch of equipment repairs.
