7/8-14 X 11" 六角頭螺絲 | 美國製造 | L9合金鋼 黃鋅 | 部分螺紋 (10 / 包)

These threads are seriously solid—the L9 alloy steel feels dense in the hand, and the yellow zinc finish has a nice, even sheen. I used them to bolt down a heavy conveyor bracket and the 11" length with partial threading gave plenty of grip without any wobble.

The yellow zinc coating looks good and the hex heads fit my wrench perfectly. I used these to secure a heavy motor mount and they held tight without any stripping. Solid fasteners for the money.

The threads cut cleanly into the tapped hole on my jig fixture, and the Grade L9 steel feels reassuringly tough under a socket wrench. Yellow zinc finish looks like it will hold up fine in my shop environment.
