M3×3mm 平頭止付螺絲 | 合金鋼 (1000入/包)

Finally, a thousand pieces in one pack means I won't be scrambling for spares mid-project. The flat point grabs nicely in the recess without slipping, and the hex socket lets me torque them down with a tiny wrench even in awkward spots.

These M3 set screws are the perfect size for securing small pulleys on my 3D printer. The alloy steel feels solid, and the flat point holds tight without marring the shaft surface. I appreciate getting a full 1000-count pack for this price.

The hex socket drive makes these a cinch to seat even in awkward spots where a standard driver won't fit, and the flat point bites down firmly without marring the shaft. A full thousand of them means I've got spares for every project for years.
