براغي تثبيت برأس كوبي M8 × 15 مم | فولاذ سبائكي مطلي بالزنك (250 / عبوة)

The hex drive on these set screws made adjusting them in a tight spot much easier than using a slotted screwdriver. The cup point grips the shaft firmly without slipping.

I was replacing a worn-out set screw on a tiller shaft and these M8 cup points held perfectly under vibration. The zinc plating looks solid too, no rust after a few weeks in a damp shed.

Just got these set screws for a jig I'm working on, and the hex socket drive makes tightening them in tight spots really easy. The cup point bites nicely into the metal surface, so I feel confident they won't loosen up. Great value for the price with 250 in the pack.
