براغي مقبس نقطة كوب M12 × 80 مم | فولاذ سبائكي (50 / عبوة)

I needed a set of M12 cup point screws for locking a collar on a shaft, and these 80mm ones held tight after just a few turns with my hex key. The alloy steel feels really solid compared to the cheaper zinc-plated alternatives I've used before.

The hex socket drive made torquing these into a tight machine frame effortless. The cup point really bites into the metal to prevent any slipping under vibration. Exactly what I needed for a stubborn alignment job.

Used these to lock down a gear hub on my milling machine and the cup point really bites into the shaft without walking. The hex socket let me get a solid torque even in a cramped spot behind the pulley. Set of fifty means I've got spares for the next project.
