براغي رأس سداسية 9/16-18 × 1-1/4" | فولاذ درجة 5 أصفر زنك | ملولبة بالكامل (50/عبوة)

The yellow zinc finish looks uniform across all fifty bolts, and the threads are clean right out of the package. I used them to mount a steel bracket and the 1-1/4" length fit perfectly without any trimming.

These bolts hold up great under torque—the yellow zinc coating looks clean and hasn't shown any wear after a week of heavy use on my trailer hitch. The hex head grips a socket perfectly, and having 50 in the pack means I've got spares for the next project.

I've been using these fully threaded 9/16-18 cap screws for rebuilding an old piece of farm equipment, and the hex head makes them super easy to torque down with a socket. They fit perfectly in the pre-tapped holes and feel solid, no stripping issues.
