براغي ضبط ذات رأس كوب 7/16-20 × 1-1/2 بوصة | فولاذ سبائكي (100 / عبوة)

These little screws have been perfect for locking down pulleys on a shaft where vibration was the enemy. The cup point bites in really well, and the hex socket held up through some serious torque without a hint of rounding.

I was worried the hex socket would strip under torque, but it held perfectly even in a tight engine bay. The cup point tip grabs deep and the alloy steel feels solid. Great mix of precision and strength.

These cup point set screws grab deep into the counterbore without any cam-out, even on a tight adjustment. The hex socket drive makes them easy to torque down in cramped spots. Exactly the grip I needed for a precision jig build.
