1-1/2-12 X 8" 六角頭螺絲 | 美國製造 | L9合金鋼黃鋅 | 部分螺紋 (4個/包)

Used these on a heavy-duty press and the L9 alloy steel held up perfectly under high torque, no stripping at all. The yellow zinc looks well applied and should resist rust well in a shop environment.

The partially threaded design made alignment a breeze when I was bolting a heavy steel bracket into place. The yellow zinc finish looks sharp and the threads cut clean, no binding at all.

These bolts are exactly what I needed for a heavy-duty jig I'm building. The Grade L9 alloy steel feels incredibly strong and the yellow zinc coating looks durable. Threads are clean and the hex head fits a standard socket perfectly.
