براغي تثبيت بنقطة نصف كلب 1/2-20 × 2-1/2 بوصة | فولاذ سبائكي (100/عبوة)

The hex socket drive made cinching these down in a tight bracket area way easier than I expected for a 2.5-inch screw. The half dog point seated cleanly into the shaft hole on the first try, and all 100 threads came through consistent and true.

I needed these for a jig I was building, and the half dog point tip held perfectly without slipping under load. The alloy steel feels really sturdy, and the hex socket took an Allen wrench without any fuss.

The hex socket drive made it easy to tighten these in a cramped machine base where a wrench wouldn’t fit. The half dog point tip seated nicely without slipping out of alignment.
