براغي رأس سداسي مقاس M16-2 × 140 مم | فولاذ فئة 8.8 أصفر زنك | ملولبة جزئياً (20/عبوة)

The hex head on these M16 screws grips the socket perfectly, making installation smooth even in tight spaces. The yellow zinc coating seems durable and consistent across all 20 pieces in the package.

Class 8.8 steel with yellow zinc is exactly what our jig needed—the hex head grabs a socket cleanly every time. These M16s have taken some serious torque without a hint of stripping, and the partial thread lets me cinch down two plates without bottoming out. Solid buy for the price.

The partial threading made all the difference when securing heavy-duty brackets to our steel frame—no struggling to get full thread engagement. These bolts torqued down smoothly without galling, and the yellow zinc finish looks clean and professional.
