براغي كاب سداسية ثقيلة 5/8-11 × 4 بوصة | صناعة أمريكية | فولاذ A307 درجة B مطلي بالزنك | ملولبة جزئيًا (90/عبوة)

Needed a dozen for a heavy equipment frame repair and these threaded in cleanly without any binding. The zinc finish looks durable and the partial threading made alignment a breeze.

The zinc coating on these bolts is uniform and thick, no flaking or thin spots like some cheaper hardware I've used. They threaded cleanly into my trailer hitch mount with no binding, and the 4-inch length was perfect for beefing up the frame.

Had to re-tap an old piece of farm equipment and these hex cap screws grabbed perfectly without binding. The zinc coating seems thick enough to resist our damp barn storage.
