براغي تثبيت ذات رأس داخلي سداسي بنقطة كأس مخددة M4 × 10 مم | سبيكة فولاذ (1000 / عبوة)

The hex socket drive made these set screws so much easier to tighten in a cramped assembly area. The knurled cup point grips the shaft firmly without slipping.

Installed these in a jig for a milling project and the hex socket drive made tightening them in tight spots really easy. The knurled cup point held the workpiece securely without any slipping, even under heavy vibration.

The knurled cup point grips the workpiece far better than I expected, so these haven't slipped once during my fixture adjustments. For a thousand pieces at this price, the alloy steel finish looks clean and the hex drive takes torque without stripping.
