براغي ضبط بنقطة كوب M14 × 25 مم | فولاذ سبائكي (50 / عبوة)

The hex socket drive made installing these in a tight motor coupling a breeze, and the cup point bit in firmly. For the price and quantity, this pack is solid value for any project needing high-torque screws.

I needed a set screw that could handle some serious vibration on a new jig I'm building, and these M14s with the hex socket drive cinched down perfectly without stripping. The 25mm length gave me just the right engagement depth, and the alloy steel feels really solid.

The cup point tip bit into the shaft firmly, no slipping even under heavy torque. For a pack of fifty M14x25mm alloy steel set screws, the price is fair and the hex socket drive makes installation straightforward in tight spots.
