M5 X 5mm 滾花杯點內六角設定螺絲 | 合金鋼 (1000入/包)

The hex socket drive on these M5 screws made adjusting my jig’s hold-down clamps much easier in those tight spots. The knurled cup point really grips the workpiece without slipping.

I needed these for a tight spot where a regular wrench wouldn't fit, and the cup point tip gripped firmly without slipping. The knurling on the set screw made installation feel secure even with oily fingers.

Bought these for swapping out some worn-down set screws on a jig, and the knurled cup point really grips tight without slipping. It feels solid, and the hex drive makes them easy to torque down even in a cramped spot.
