براغي رأس سداسية 1-1/2-6 X 7" | صناعة أمريكية | درجة L9 من سبائك الفولاذ مطلي بالزنك الأصفر | خيط جزئي (4/عبوة)

The partially threaded design made installation much easier on my press jig, and the yellow zinc held up well under a lot of torque. These are exactly what I needed for heavy-duty work—solid and reliable.

Picked up a pack for a heavy-duty jig I'm building, and the Grade L9 alloy steel feels seriously tough. The yellow zinc finish looks clean and the 1-1/2 inch length worked perfectly for the 7 inch bolt I needed. Threads were clean right out of the package, no binding.

Installed these on a press machine at work and they seated perfectly with a socket wrench. The yellow zinc coating seems like it’ll hold up better than the old black oxide ones I was using.
