براغي تثبيت ذات رأس سداسي نقطة كوب مخددة M5×10mm | فولاذ سبائكي (1000/عبوة)

I needed some set screws for a jig I was building, and these M5 x 10mm knurled cup point screws hold firm even with the hex socket drive under heavy torque. The alloy steel feels solid, and the knurling really bites into the metal surface without slipping.

The knurled cup point grips the workpiece far better than I expected, so these set screws stay put even under constant vibration. I’ve already used about 300 of them for jig fixtures and haven’t had a single one strip or back out.

The hex socket drive made tightening these in a cramped machinery panel much easier than I expected. All hundred screws in the pack had clean, consistent threads, which saved me a lot of time.
