M10 X 25mm フラットポイント六角穴付き止めねじ | 合金鋼 (100個入り)

Honestly, I was a bit worried about stripping the hex socket on a few of these, but the socket drive bit holds the wrench firmly even when I’ve got them torqued down in a tight spot. The flat point seats nicely against the shaft, and the alloy steel feels solid for the price.

These flat point set screws fit perfectly into the blind holes on my new shaft coupling, and the hex socket let me torque them down securely without any stripping. The alloy steel feels solid, and the M10x25mm size was exactly what my project needed.

I needed a set screw that wouldn't budge under vibration, and the hex socket drive lets me really torque these down without stripping. Alloy steel feels solid, and the flat point bit into the shaft nicely on my first job.
