براغي مجموعة رأس سداسية داخلية بنقطة كوب M8 × 16 مم | فولاذ سبائكي مطلي بالزنك (250 / عبوة)

The cup point tip on these screws really digs in securely, making them perfect for tight spaces where a regular bolt won't fit. I used them on a jig fixture and they held fast under heavy clamping pressure.

Finally, a set screw that actually bites into the shaft without rounding off—the cup point on these M8s is sharp and holds tight. I used them to lock a pulley on a motor shaft, and the hex socket made it easy to get the torque right in a cramped spot.

These do the job for securing small parts, though the zinc coating looks a bit uneven on a couple of fasteners in the bag. The hex drive works fine in my adjustable fixture, and the cup point holds well enough for my needs.
