براغي تثبيت بنقطة نصف كلب | 7/16-20 × 1" | فولاذ سبائكي (100 / عبوة)

Installed these into a tight corner on a jig, the hex socket drive really saved the day since I couldn't fit a regular wrench in there. All 100 pieces came uniformly threaded and the alloy steel feels plenty durable for shop use.

The half dog point tip seated perfectly into the mating hole on my first try, and the alloy steel feels dense and sturdy for the price. I grabbed a hundred of these for a fixture build, and every single one had clean, sharp threads without any burrs or wobble in the hex socket.

The hex socket drive handled high torque without stripping, even when I had to thread these into a cramped bracket. All 100 pieces arrived clean and the half dog point seated perfectly on the first try.
