براغي ضبط مقبس بنقطة كوب M12 × 14 مم | فولاذ سبائكي (250 / عبوة)

The hex socket drive is perfect for getting these set screws snugged into tight spots without rounding off. Cup point bites into the shaft nicely and holds secure, and for a full box of 250 alloy steel screws, the price feels solid.

Exactly what I needed for locking down a pulley on a motor shaft—the hex drive made installation in that tight spot a breeze. The cup point bit into the shaft nicely without slipping.

Used these for securing a gear hub on a custom bike build, and the cup point tip grips like crazy even under vibration. The hex socket drive made installation in a tight spot a breeze. Solid fasteners for the price.
