براغي رأس سداسي 9/16-18 × 6-1/2 بوصة | صناعة أمريكية | فولاذ درجة 8 مطلي بالزنك الأصفر (70/عبوة)

These bolts are a solid upgrade for heavy equipment repairs I've been doing. The Grade 8 steel feels noticeably tougher than the hardware store stuff, and the yellow zinc finish hasn't shown any rust yet. Really pleased with the quality for the price.

I needed a full 6-1/2" length for a heavy machinery repair, and these Grade 8 bolts handled the torque perfectly with no stripping. The hex head gave my socket a solid grip, and the yellow zinc coating looks durable.

The threads cut clean and the yellow zinc finish looks uniform across all 70 pieces, which honestly impressed me for the price. I needed these for a heavy equipment frame and the Grade 8 rating gives me confidence they won't snap under load.
