براغي رأس سداسي 3/4-10 X 3 بوصة | صناعة أمريكية | درجة L9 سبائك فولاذية زنك أصفر | خيط جزئي (20 / عبوة)

I needed these for a heavy machinery repair and the partially threaded design made alignment a breeze. The hex head grabbed securely with my socket wrench, and the yellow zinc finish looks tough.

These hex cap screws have a nice, solid feel to them—the yellow zinc finish looks clean and durable. I used them to secure a heavy jig on my mill table, and the Grade L9 alloy steel handled the torque without any issues. They're exactly what I needed for industrial-grade fastening.

The yellow zinc coating on these has a really nice, even finish. They seated perfectly in my press jig with no binding at all. For heavy-duty industrial use, these L9 bolts feel like they’ll hold forever.
