M3 X 12mm 錐點內六角止付螺絲 | 合金鋼 (100顆/包)

The cone point bites into the shaft cleanly, and the alloy steel held up without stripping when I torqued them in with a hex key. Exactly the right grip for a 3mm screw this length, and a hundred of them means I've got spares for the next job.

The hex socket drive made it easy to tighten these into tight corners on my 3D printer bed leveling setup. They feel sturdy and solid, definitely worth the small investment.

These M3 cone point screws hold perfectly in my 3D printer's hotend assembly. The hex socket drive lets me torque them down precisely in that cramped space. Solid alloy steel, zero stripping issues so far.
