براغي رأس مقبس سداسي M12 × 30 مم بنقطة كوب محززة | فولاذ سبائكي (100 / عبوة)

Finally got these for a jig I’m building, and the hex socket drive makes torquing them down in tight spots a breeze. The alloy steel feels sturdy, and they hold firm without stripping.

The knurled cup point really bites into the surface, so I trust these set screws to hold firm under vibration. They threaded cleanly into the M12 hole without any binding, and the hex drive gave me good torque in a cramped spot.

The hex socket drive on these M12 screws gives a really solid grip without slipping, which made installing them in a tight spot much easier than I expected. The knurled cup point holds firmly against the shaft even after several adjustments. Solid value for a hundred-pack.
