3/4-16 X 2-3/4" براغي رأس سداسي | فولاذ درجة 5 زنك أصفر | ملولبة جزئياً (25 / عبوة)

The hex heads fit my socket perfectly and the zinc coating looks clean and consistent across all 25 pieces. Used them to secure a motor mount and the partial threading made alignment much easier than fully threaded bolts would have.

I needed a set of heavy-duty bolts for a trailer hitch project, and these partially threaded ones gave me just the right grip length. The hex head fit perfectly with my socket wrench, and the zinc coating seems tough enough to handle outdoor exposure.

The yellow zinc finish on these Grade 5 bolts looks great and hasn't shown a speck of rust after a week of outdoor use. The partial threads grab cleanly, and the hex heads take a socket without any stripping. Exactly what I needed for mounting a motor bracket.
