براغي ضبط رأس مقبس بنقطة كوب مخددة M12 × 25 مم | فولاذ سبائكي (100 / عبوة)

Installed these on a few jigs and the cup point really bites into the shaft without slipping. The alloy steel feels solid and the 25mm length was perfect for my setup.

Finally, a set screw that doesn't strip under heavy torque—the hex socket drive held perfectly when I tightened them into a machine base. They're about the length I expected for M12 x 25mm, and the alloy steel feels solid.

The knurled cup point really grips the surface without slipping, which is exactly what I needed for a stubborn alignment job. All 100 screws arrived uniformly threaded and the alloy steel feels plenty sturdy for repeated adjustments.
