براغي رأس سداسي مقاس 9/16-12 × 1 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة بالكامل (50 / عبوة)

The yellow zinc coating on these grade 5 screws looks really clean and even, plus they threaded smoothly into my equipment frame without any binding. Exactly what I needed for a solid, heavy-duty fastening job.

The hex heads on these bolts grabbed my socket perfectly, no slipping at all during installation. The yellow zinc coating looks clean and uniform across all 50 pieces, which is exactly what I needed for a visible machinery repair.

Used these to secure a new motor mount on my milling machine and the grade 5 steel handled the torque without stripping. The yellow zinc coating gives them a nice, corrosion-resistant finish that should hold up in my shop.
