براغي ضبط بنقطة كوب 7/16-14 × 3/4 بوصة | فولاذ سبائكي مجلفن (100/عبوة)

Used them to secure a sprocket on a custom rig, and the cup point bit into the shaft cleanly without slipping. The zinc coating held up fine under the wrench, and all 100 threaded smoothly. Exactly what I needed for the price.

The hex drive grabbed perfectly even in that cramped spot on the shaft. These cup points really bite into the metal without stripping, and the zinc coating looks clean and rust-free right out of the package.

I needed a high-torque set screw for a heavy-duty coupling, and the hex socket drive made installation straightforward even in a tight spot under the machine. The cup point bit into the shaft firmly without slipping. Good value for a full pack of 100.
