براغي رأس سداسي 7/16-14 × 2 بوصة | صناعة أمريكية | فولاذ سبائكي درجة L9 بزنك أصفر | ملولبة جزئيًا (50 / عبوة)

The partially threaded design made installation on my equipment frame much easier since the threads only engage where needed. These hex heads took a socket wrench without slipping, and the L9 alloy steel feels solid.

The yellow zinc finish on these Grade L9 screws held up perfectly during a heavy machine assembly job, no chips or peeling even with a socket wrench torquing them down. The partial threading gave just the right grip for our equipment frame.

These bolts threaded smoothly into my tractor's frame without binding. The partially threaded shaft is a nice touch, giving a solid clamp without having to stack washers.
