براغي رأس سداسي 3/8-24 × 5" | فولاذ درجة 5 بزنك أصفر | ملولبة جزئيًا (50 / عبوة)

The threads were clean and the hex heads seated perfectly in my socket without any slipping. These grade 5 bolts feel solid enough for the heavy equipment mount I’m working on, and the partial threading made alignment easier than I expected.

I needed a few of these for a trailer hitch repair and the partially threaded design made installation a breeze. The hex heads seated perfectly with a standard socket, no stripping or issues at all.

The yellow zinc coating on these Grade 5 bolts really resists rust well, even in my damp workshop. I installed them on a heavy-duty bracket and the partial threading gave me exactly the grip I needed without extra slop.
