براغي رأس سداسي 7/16-14 × 3 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة جزئياً (275 / عبوة)

These bolts threaded smoothly without binding, and the yellow zinc coating looks tough enough for outdoor machinery use. The partial threading gave me just the right grip for mounting a motor bracket. Exactly what I needed for heavy assembly work.

Bought these for securing a heavy conveyor section and the hex head gave my socket wrench plenty of bite without stripping. The yellow zinc coating looks solid and should hold up fine in the shop environment.

The partial threading is a lifesaver when I need to clamp two plates together without the threads chewing up the hole. The yellow zinc coating has a consistent finish across all 275 pieces, and the hex heads grab a socket cleanly every time.
