M12-1.75 X 280mm 六角頭螺絲 | 8.8級鋼鍍鋅 | 部分螺紋 (15入/包)

Picked up these for a piece of farm equipment I'm rebuilding, and the partially threaded design grabbed just right for the heavy lock washer I needed. The hex head gave my socket a solid grip without slipping.

These 280mm bolts are exactly what my press build needed, and the zinc plating looks clean and uniform across all 15 pieces. The partial thread let me clamp two thick flanges together without wasting grip length, and the hex heads took a socket without any rounding.

Grabbed these for a jig project and the partial threading made alignment way easier than expected. The zinc coating seems durable and the hex head sat tight with a socket. Just what I needed for a heavy duty machinery repair.
