براغي رأس سداسي 5/16-18 × 6-1/2 بوصة | صناعة أمريكية | فولاذ درجة 8 مطلي بالزنك الأصفر (250/عبوة)

The yellow zinc finish on these looks great and held up fine during assembly, no marring or rust flakes. Each of the 250 bolts threaded cleanly into my equipment frame, and the Grade 8 rating gives me confidence they won’t snap under load. Even the packaging was sturdy enough to store the extras in

I needed a longer bolt for a custom bracket on a heavy press, and these 6-1/2" grade 8 screws threaded in smoothly without any binding. The zinc coating looks consistent and should hold up fine in my shop.

These bolts cinched down evenly on my tractor's frame with no binding. The 6-1/2 inch length was exactly what I needed for that thick bracket assembly, and the grade 8 steel feels solid.
