براغي ضبط رأس كروي مدبب 1/4-20 × 1-1/4" | فولاذ سبائكي (100/عبوة)

The knurled cup point tip seated perfectly flush in my jig fixture, and the alloy steel finish shows no sign of stripping yet. These are exactly what I needed for a tight-access adjustment joint.

The hex socket drive made torquing these down in a cramped bracket way less of a struggle than I expected. All 100 pieces arrived with clean threads and the knurled cup point seated firmly without any slip.

The knurled cup point grips the shaft like a vice—no slipping even after a full day of vibration. The hex socket drive made final torque adjustments in cramped spots genuinely effortless, and all 100 arrived clean and uniform.
