براغي رأس سداسي مقاس 1/2-13 × 1 بوصة | فولاذ درجة 8 مطلي بالزنك | ملولبة بالكامل (450 / عبوة)

I needed to replace the bolts on a heavy-duty jig, and these Grade 8 hex heads seated perfectly without stripping. The zinc coating feels substantial, and the full threading made installation a breeze.

Put a new ball hitch on my trailer and these grade 8 bolts threaded in smooth and held tight without any binding. The zinc coating looks clean and should resist rust from road salt.

I’ve been using these for heavy equipment repairs and the hex heads hold up perfectly under a torque wrench without stripping. The zinc coating looks solid and the flat packaging made them easy to store.
