براغي رأس سداسية 5/16-18 × 1 بوصة | فولاذ درجة 5 أصفر زنك | ملولبة بالكامل (1400 / عبوة)

The hex heads fit my socket set perfectly, and the yellow zinc finish looks clean and corrosion-resistant right out of the box. I used these for mounting heavy equipment brackets, and the 5/16-18 thread held solid without any stripping. For a bulk pack of 1400, the consistent quality makes these a n

For the price, these bolts have a consistent thread and the yellow zinc coating looks uniform across all 1400 pieces. I used them to rebuild a conveyor section and every one drove cleanly without any binding.

Needed a bulk supply for assembly line repairs and these grade 5 bolts threaded smoothly into all the tapped holes. The yellow zinc coating looks consistent across the whole package.
