براغي رأس سداسية مقاس 1"-8 × 9" | فولاذ درجة 8 مطلي بالزنك | ملولبة جزئيًا (15/عبوة)

The threads are clean and cut smoothly, and the zinc plating on these Grade 8 bolts has a nice, consistent finish. They fit perfectly into my heavy equipment’s mounting flange without any wobble.

These bolts held firm when I torqued them down for a heavy press build; the Grade 8 zinc plating looks clean and didn't chip during installation. Exactly what you need for machinery assembly.

Pulled one out to check the threads and they're clean and consistent, no burrs. The partial threading made it easy to set the initial depth on my press project. Really solid feel when you torque them with a wrench.
