M2 X 3mm 杯頭內六角止付螺絲 | 合金鋼 (1000顆/包)

I needed tiny set screws for a precision jig, and these M2 cup points bite perfectly into the metal without slipping. The alloy steel feels tough enough to hold adjustments even in a vibrating setup.

The hex socket drive makes these a breeze to torque down even in the tightest spots, and the cup point grips the shaft firmly without slipping. A full thousand in the pack means I won't be running out mid-project anytime soon.

These screws fit perfectly into a tight spot where I needed high torque, and the hex socket drive made installation much more controlled than using a standard Phillips. The cup point tip also held the screw in place while I started threading it.
