M30-3.5 X 180mm 六角頭螺絲 | Class 8.8 鋼本色 | 部分螺紋 (2 顆/包)

Needed something heavy-duty for a machine base and these 180mm bolts did not disappoint. The hex head gave a solid grip with my socket wrench, and the partial threading made alignment much easier.

The threads engaged cleanly with the nut even with the partial threading, and the hex head gave my socket a solid, wrenching grip without any slipping. These are hefty pieces of steel that feel like they'll hold up well on my press setup, and two in the pack was exactly what I needed.

Used these to bolt down a heavy jig frame, and the partial threading made alignment way easier than I expected. They’re solidly built for the price, and the hex heads grab a socket without any slip.
