M20-1.5 X 70mm 六角頭螺絲 | 等級10.9 鋼鍍鋅 | 全螺紋 (25/包)

Used these to secure heavy machinery feet to the floor and the 10.9 grade steel feels rock solid even under full torque. The 25-piece pack gave me enough spares for future projects. Exactly what I needed for heavy-duty assembly.

The hex head made it easy to grip with a socket wrench for tightening down my press frame. These fully threaded M20 bolts held firm at the rated torque spec. A solid choice for heavy assembly work.

Needed to replace the old bolts on a press frame, and these class 10.9s torqued down without a hint of stripping. The fully threaded length gave me plenty of grip, and the zinc coating looks clean under the shop lights. Worth the money for a job that has to hold.
