M18-2.5 X 45mm 六角頭螺絲 | 10.9 級鋼素面 | 全牙（每包 150 顆）

Used these to bolt down a heavy press at the shop and the 45mm length was spot-on. The Class 10.9 steel feels substantial and the hex heads gripped the socket firmly without any stripping.

The threads are cut clean and the hex heads seat perfectly with a standard socket, no stripped corners after torquing them down on our press frame. For the price per box, you’re getting a solid Class 10.9 stock that’s held up through a full week of heavy assembly work.

Used these to rebuild the feed mechanism on a punch press and every single one seated cleanly, no galling. The 10.9 hardness held up to the torque wrench without a hint of stretch. At this price for a full box, I’m stocking up for the next job.
