M6 X 25mm براغي تثبيت ذات تجويف سداسي بنقطة مسطحة | سبائك الصلب (250/عبوة)

I needed set screws that wouldn't strip under heavy torque, and the alloy steel construction on these feels really solid. They fit perfectly into my jig's adjustment points, and the flat point grips securely without marring the surface.

The hex socket drive is a lifesaver when you're working in tight spots—I could barely fit a regular driver in there. These M6 screws grabbed fast and the alloy steel feels tough enough for the job. Exactly what I needed for my project.

Used a few of these to secure a stubborn pulley on a motor shaft, the flat point bit into the keyway perfectly. The hex socket held up fine under a good amount of torque without stripping.
