براغي ضبط ذات رأس مخدد ونقطة كوب M6 X 12mm | فولاد سبائكي (1000 / عبوة)

I had to swap out a stubborn set screw on a machine jig, and these M6x12mm ones held up perfectly under the hex drive torque. The knurled cup point grips the shaft firmly without slipping. For a thousand pieces, the price is unbeatable.

The knurled cup point really bites into the shaft, so these set screws hold tight without stripping. I used a full bag on a jig frame and haven't had one back out yet.

The hex socket drive made tightening these in a confined spot on my workbench much easier than I expected, and the knurled grip held firm without slipping. I've already used about forty from the pack, and every single one threaded cleanly.
