M10 X 40mm مسامير تثبيت ذات رأس مقبس بنقطة كلب كاملة | فولاذ سبائكي (100/عبوة)

The hex socket drive grabbed onto my Allen key with zero wobble, which made torquing these down in a cramped machine frame way easier than I expected. The full dog point seated perfectly into the alignment hole on the first try, and the alloy steel feels solid enough to trust under real load.

I needed some hardened set screws for a jig I'm building, and these alloy steel ones with the full dog point bite into the shaft perfectly without slipping. The hex socket made them easy to tighten with my T-handle Allen key.

The hex socket drive makes these easy to tighten even in awkward spots, and the full dog point seats firmly. Took off one star because a few screws in the pack had slightly uneven threading, but the alloy steel feels sturdy overall.
