براغي رأس سداسي 1-1/4-12 × 5 بوصة | صناعة أمريكية | درجة L9 سبيكة فولاذية صفراء زنك | ملولبة جزئيًا (6/عبوة)

The partially threaded design made these much easier to install on my machinery jig than fully threaded bolts would have been. The yellow zinc coating looks good and the Grade L9 steel feels seriously tough.

I needed these for a heavy equipment repair and the 5" partially threaded length was exactly what the job called for. The hex head sat perfectly in my socket without any wobble, and the yellow zinc finish looks like it'll resist rust well.

Finally, some 1-1/4-12 bolts that don't strip under heavy torque; the Grade L9 alloy steel feels way tougher than the hardware store stuff. These are a perfect fit for my press jig, and the partial threading saved me from having to cut them down.
