M36-4 x 200mm 六角頭螺絲 | 8.8 級鋼 普通 | 部分螺紋 (4 顆/包)

Put four of these into a welded frame I was repairing, and the partially threaded shank made alignment much easier. The hex heads grabbed perfectly with my impact wrench, and they held up under heavy load without any issues.

Needed these for a heavy-duty jig I was building, and the 200mm length with partial threading gave me just the right grip depth without bottoming out. The class 8.8 steel felt solid cranking them down to torque.

Went in smooth with a socket wrench on a heavy press assembly—the threads were clean and caught right away. Even at this size, the hex heads gripped well without any rounding.
