براغي ذات رأس سداسي 1-1/4-12 × 6" | صنع في الولايات المتحدة | درجة L9 فولاد سبائكي مع زنك أصفر | ملولبة جزئيًا (6 / عبوة)

The yellow zinc coating on these screws held up perfectly during the assembly of a heavy-duty press jig. They torqued down smoothly with a socket, and the partial threading made alignment a breeze. Just the right grip for industrial work.

The partially threaded design made lining up the frame a breeze, and the yellow zinc finish looks clean against the steel. These Grade L9 bolts feel rock solid in the hand, and the hex head grabbed the socket with zero slip. Pricey for six, but the US-made quality is obvious.

I needed heavy-duty bolts for a trailer hitch repair, and the L9 alloy steel on these handled the torque without any issue. The yellow zinc coating looks clean and seems like it'll resist rust well too.
