M10 X 70mm 杯端內六角止付螺絲 | 合金鋼（50 / 包）

The hex socket drive took the torque without stripping, which was my main worry with cheaper sets. All fifty arrived clean with the cup points properly machined, and they’ve held firm in a tight mounting bracket since day one. Exactly what I needed for the job.

I needed a hex socket drive for a tight spot under my car's dash, and these M10 screws let me crank them down without slipping. The alloy steel feels solid, and the cup point tip seated perfectly against the metal bracket. Worked exactly as I hoped on a tricky assembly.
