براغي رأس مقبس نقطة كوب M6 × 15 مم | فولاذ سبائكي (500 / عبوة)

I needed to lock a pulley onto a motor shaft, and these M6 set screws with the hex socket drive made it easy to torque them down properly. The alloy steel feels solid, and the cup point really digs in without stripping.

The cup point grips the shaft way better than the flat-tip screws I used before, and the hex drive let me torque them down in a tight spot without stripping. Ordered the 500 pack for a job and went through half of them already, zero complaints.

These M6 set screws are exactly what I needed for a machine tool adjustment where the hex socket made installation easy even in a tight spot. The cup point bit in firmly without slipping, and the alloy steel feels solid for the price.
