7/8-14 x 5" 六角頭螺絲 | 美國製造 | L9級合金鋼黃色鍍鋅 | 部分螺紋 (15 / 包)

Couldn't believe how straight these threads ran when I torqued them on a heavy-duty jig fixture. The hex heads seated perfectly with a standard socket, and the partial threading made alignment a breeze.

Great fit for my press brake repair—the partially threaded shank let the clamp sit flush without binding. Yellow zinc finish looks tough and hasn't marred from the socket wear. These L9 bolts feel heavier than the grade 8s I used before.

These L9 bolts are exactly what I needed for a heavy equipment repair, the partially threaded design made alignment much easier. The yellow zinc coating looks tough and the hex head fits a socket perfectly.
