براغي رأس سداسي 5/8-18 × 4-3/4" | فولاذ درجة 8 بزنك أصفر | ملولبة جزئيًا (75 / عبوة)

Needed these for a heavy equipment repair and the grade 8 strength held up perfectly under torquing. The partially threaded design made alignment a lot easier than full-thread bolts would have.

The hex heads seated perfectly with a socket wrench on our press assembly, and the yellow zinc finish looks like it’ll hold up fine on the shop floor. Grade 8 strength gives me peace of mind on the load-bearing joints.

The partially threaded design made installation a breeze on my equipment frame—these Grade 8 bolts really grip tight. They're noticeably heavier than standard hardware I've used before, which gives me confidence in the load.
