مسامير رأس سداسي 5/16-18 × 7/8 بوصة | فولاذ درجة 8 زنك أصفر | ملولبة بالكامل (1500/عبوة)

Pulling these out of the box, the hex heads are sharp and consistent across the whole batch, which makes them easy to drive with a socket. The yellow zinc coating looks even and should hold up well in my shop equipment. Glad I went with the 1500 count for this project.

Needed a bulk supply for rebuilding some farm equipment, and the Grade 8 strength is exactly what I was looking for. The hex heads drive cleanly with a socket, and having 1500 pieces in one box saves me multiple trips to the store.

Packed a few of these into some heavy equipment brackets and the Grade 8 strength held up without any stripping. The yellow zinc coating looks clean and seems like it'll resist rust fine.
