براغي رأس سداسية 1/2-13 × 1" | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة بالكامل (400/عبوة)

I needed a hefty batch of 1/2-13 bolts for a production line jig, and these fully threaded hex heads held up perfectly under the torque without stripping. The yellow zinc coating is a nice bonus for corrosion resistance in a slightly damp shop.

These arrived earlier than expected, and the zinc coating has a nice, uniform finish that makes them look clean right out of the box. I used a full row to bolt down some equipment frames, and every single one threaded smoothly with no binding.

I needed a full box for a large frame assembly and these hex heads drove smoothly with no burs or stripped threads. The yellow zinc coating looks uniform and should hold up fine in shop conditions.
