براغي رأس سداسي 1-1/4-7 × 11 بوصة | صناعة أمريكية | فولاذ سبائكي درجة L9 مطلي بالزنك الأصفر | ملولبة جزئيًا (4/عبوة)

Installed these on a heavy-duty press table at work and the Grade L9 alloy held up perfectly through the first full shift. The partial threading made alignment in the predrilled holes much easier than expected. Exactly the quality I look for in industrial fasteners.

The threading is clean and the hex head fits a wrench perfectly—no stripped corners on these. I used them to bolt down a heavy conveyor bracket and they’ve held rock solid under vibration. Grade L9 yellow zinc feels tough, and the partial thread made alignment a lot easier.

Used these for mounting a heavy jig on a drill press table, and the partially threaded shaft made alignment a breeze. The yellow zinc coating on these Grade L9 alloy steel screws looks and feels durable, too.
