M18-2.5 X 140mm 外六角螺絲 | 8.8級鋼 原色 | 半牙 (60顆/包)

These hex head screws drove in cleanly with my impact wrench, and the 60-count package is exactly what I needed for a large assembly job. The 8.8 steel feels solid for the price.

The partial threading on these M18-2.5s is perfect for clamping down thick flanges without bottoming out, and the class 8.8 steel feels properly hardened when you torque them. I've used about forty of them on a jig build so far and not a single stripped head or snapped shank. Finished the whole box

The hex head on these M18-2.5 cap screws gave my socket wrench a solid grip without any slippage, which made assembly go smoothly. I've already used half the pack for securing heavy machinery mounts.
