براغي ضبط ذات رأس أسطواني مع نقطة كروية محززة 3/8-16 × 2 بوصة | فولاذ سبائكي (100 / عبوة)

The knurled cup point really bites into the shaft—no slipping even after a few days of vibration. At 2 inches long, they gave me just enough thread engagement for a heavy bracket install.

The hex socket drive made installing these in a tight spot on my workbench actually easy. They feel solid, and the knurled cup point gives them a clean, professional look.

The knurled cup point grips way better than standard flat tips, so these actually stay put under vibration. I used them to lock down a jig on my mill and the hex socket made final torque adjustments in a cramped spot a breeze. Pack of 100 should last me years.
