براغي ضبط بنقطة كوب M3 × 8 مم | فولاذ سبائكي مطلي بالزنك (1000 / عبوة)

Finally got around to replacing all the worn set screws on my 3D printer's hotend assembly. The hex socket drive made adjusting them in those tight spots a breeze, and the cup point tip grips firmly without slipping. Exactly what I needed for high-torque adjustments.

Had to replace a stripped set screw on a piece of machinery and these M3s fit perfectly in the tight hex socket without slipping. The zinc plating looks good and should resist rust in the shop.

The cup point on these M3 screws really bites into the shaft, and the hex socket drive makes adjustments in tight spots easy. Fast shipping and a solid count for the price.
