براغي رأس سداسي 1/2-13 × 5" | درجة 5 فولاذ مطلي بالزنك الأصفر | ملولبة جزئيًا (125 / عبوة)

The partial threading on these 1/2-13 x 5" bolts is exactly what I needed for a tight fit where full threads would have bottomed out. The yellow zinc coating looks uniform and the hex heads seated cleanly with a socket wrench.

Pulled these out for a heavy jig assembly and the partially threaded shank made it much easier to get a tight fit. The yellow zinc finish looks clean and hasn’t shown any rust after a few days in a damp shop.

The 5-inch length is spot-on for aligning thicker steel plates, and they thread smoothly without any binding. Partially threaded design keeps the grip tight where it counts, and the hex heads grab a socket with zero stripping issues.
