M12 X 12mm 錐端內六角止付螺絲 | 合金鋼 (100個/包)

The cone point on these M12 screws bites in really well, and the hex drive lets me torque them down firmly in tight spots without stripping. This whole pack is solid alloy steel too, so I've got plenty for future projects.

These set screws fit perfectly into the adjustment ports on my milling machine’s gibs. The cone point bites nicely into the mating surface, and the hex drive lets me dial in torque precisely without stripping the socket.

Finally found cone points that actually bite into the shaft without slipping. The hex socket drive made installation a breeze in that cramped machinery area.
