براغي ضبط بنقطة كوب مخددة M12 × 40 مم | فولاذ سبائكي (50 / عبوة)

Put these in with a hex key and the knurled cup point really bites down hard—no slipping after a full day of vibration on the mill. The alloy steel feels tough, and at this price for a pack of fifty, I’m set for a long time.

The knurled cup point on these M12 set screws really locks into place without slipping. I used them on a jig that needs constant adjustment, and the hex socket drive makes it easy to get a firm grip even in tight spots. Solid build quality for the price.

I needed a set screw that wouldn’t strip out during adjustment, and these M12 x 40mm knurled cup points bite into the surface just right for a secure hold. They fit perfectly in my jig fixture and the alloy steel feels solid.
