براغي رأس سداسي M10-1.5 × 50 مم | فولاد درجة 10.9 مطلي بالزنك الأصفر | ملولبة بالكامل (100/عبوة)

These bolts are perfectly formed, with sharp threads that bit cleanly into the steel frame I’m repairing. The hex heads let me torque them down to spec without any worry of stripping.

Had to swap out some old bolts on a press, and these class 10.9 screws held up perfectly under heavy load—no stripping or bending. The yellow zinc coating also seems more durable than the plain steel ones I’ve used before.

The threads are clean and consistent all the way down, and they seat nicely in a tapped hole without binding. Only wish the hex head had slightly deeper drive sockets for stubborn applications, but they hold up well under moderate torque.
