براغي تثبيت بنقطة كوب 3/8-24 × 2-1/4" | فولاذ سبائكي (100/عبوة)

I needed a full 2-1/4" length to reach through a thick coupling, and these alloy steel screws fit perfectly. The hex socket drive made tightening them in that tight spot a breeze.

The cup point on these set screws bit into the shaft perfectly without slipping, and the hex socket drive made installation in a tight spot much easier than I expected. At 2-1/4 inches long, they’re exactly what I needed for my project.

I needed a full-length set screw for a stubborn sprocket, and these alloy steel ones drive home with no stripping. The cup point bit into the shaft nicely, and the whole pack has consistent threading.
