براغي تثبيت برأس كوبي M16 × 50 مم | فولاذ سبائكي (50 / عبوة)

The hex socket drive grabbed securely even in a really tight spot behind the motor mount. I needed these for a heavy-duty jig build, and the cup point tip held firm without any slippage. Exactly the quality I was hoping for.

I needed a really precise way to lock a gear onto a shaft, and these M16 set screws with the hex socket let me get a solid grip in a cramped spot without stripping anything. The cup point definitely digs in and holds firm, which is exactly what I wanted for the torque.

Used a few of these to lock down some heavy machinery guards. The cup point really bites into the shaft without damaging it. Wish the package had a few extra washers included for the price.
