براغي تثبيت ذات نقطة كوب M3 × 16 مم | سبائك الصلب مطلية بالزنك (500 / عبوة)

The cup point bites into the shaft nicely, and the zinc plating held up fine when I used them to lock a collar on a motor mount. Pack of 500 means I won’t run out mid-project—torqued them with a 1.5mm hex bit and they didn’t strip.

The hex drive let me torque these down securely in a tight spot without stripping. Cup point bites nicely into the shaft, holding everything snug. Pack of 500 should last me through several projects.

I needed a reliable set screw for a collar on a small spindle, and these M3x16 cup points work perfectly. The hex drive really lets you get them tight without stripping. This pack of 500 will last me for years.
