براغي رأس سداسية 5/8-11 × 4 بوصة | فولاذ درجة 5 زنك أصفر | خيط جزئي (90/عبوة)

I needed these for a trailer hitch repair and the partial threading made aligning the nut much easier. The hex head grabbed perfectly with my socket and all 90 bolts in the pack were consistent in quality.

I needed a full box of these for a machinery rebuild, and the partial threading on these 5/8-11 screws made alignment in tight spots much easier. The hex heads held up well under torque without any stripping.

The yellow zinc coating on these Grade 5 bolts looks really sturdy and hasn't shown any rust after a week of outdoor use on my trailer hitch. They threaded smoothly into the pre-tapped holes without any binding, which was a relief. Exactly what I needed for heavy-duty equipment assembly.
