براغي رأس سداسي 7/8-9 × 7 بوصة | فولاذ درجة 5 زنك أصفر | خيط جزئي (30 / عبوة)

The threads engaged smoothly on my milling machine's bracket — no cross-threading or binding at all. For a 7-inch bolt, the yellow zinc finish looks consistent and corrosion-resistant.

Used these for a heavy equipment repair and the grade 5 steel handled the torque perfectly. The yellow zinc coating looks good and hasn't shown any rust after a few weeks.

The hex heads grabbed my socket wrench cleanly on a stubborn piece of equipment, no stripping or slipping. The partial threading seated perfectly against the load, and the yellow zinc finish hasn't shown a speck of rust after a month outside.
