براغي رأس سداسي 5/8-18 × 6 بوصة | درجة 5 فولاذ مطلي بالزنك الأصفر | ملولبة جزئياً (25 / عبوة)

The hex heads seat perfectly in a socket and the yellow zinc finish looks clean on my equipment. Threads ran smooth all the way in with a wrench, and the partial threading gave me the grip I needed for a solid clamp.

I needed some heavy-duty bolts for a trailer hitch repair, and these hex head screws have a nice tight grip with the partially threaded design. The yellow zinc coating looks solid against rust, and all 25 pieces came with clean threads that fit my wrench perfectly.

The threads were clean and uniform across all 25 bolts, which saved me time during assembly. These hex heads grabbed my socket perfectly without any slipping, and the yellow zinc coating looks like it'll resist corrosion well. Exactly what I needed for mounting a heavy steel bracket.
