براغي رأس سداسي 1/2-20 × 3" | صناعة أمريكية | سبائك فولاذية درجة L9 زنك أصفر | خيط جزئي (50 / عبوة)

Needed some bolts that could handle higher torque on a press build, and these L9s definitely deliver. The yellow zinc coating looks good and the partial threading makes alignment easier.

I've been using these for heavy equipment repairs, and the partial threading makes assembly much faster when you need a shoulder bolt. The yellow zinc coating seems thicker than the usual hardware store stuff too.

Used these to bolt down a heavy press at the shop—the Grade L9 alloy steel feels incredibly strong and the yellow zinc coating looks like it'll hold up. The partial threading made it easy to get a good bite without bottoming out in the blind hole.
