براغي تثبيت M24 × 30 مم بنقطة كأسية | فولاذ سبائكي (25/عبوة)

The cup point on these screws seated perfectly flush with my work surface, which was exactly what I needed. They held firm under my impact driver without any stripping.

Finally loosened a stubborn seized bolt on my truck's frame without any damage to the screw, and the hex socket drive made getting the last torque turn effortless. The cup point really bites into the metal, so I feel confident they won't vibrate loose.

The alloy steel feels really strong, and the cup point bit into the shaft perfectly without slipping. I used these to secure a pulley on a motor mount, and they held tight even under vibration.
