براغي مقبس نقطة كوب M16 × 16 مم | فولاذ سبيكة (100 / عبوة)

I needed a strong set screw for a heavy-duty machinery repair, and these M16 cup point ones bit in perfectly with the alloy steel holding tight under torque. The hex socket drive made installation in that cramped spot much easier than I expected.

The hex socket drive grabbed perfectly even in a tight engine bay spot where I couldn't swing a wrench. These M16 cup point screws held firm under the vibration without any stripping. Exactly what I needed for a precise mechanical adjustment.

Tightened a stubborn pulley with zero slipping—the hex socket drive grips well even in that cramped corner. Alloy steel feels dense and durable, no stripped edges after a full torque session. Exactly what I needed for the job.
