1-1/4-7 x 9吋 六角頭螺絲 | 美國製造 | L9級合金鋼 黃鋅 | 部分螺紋 (6入/包)

The hex head on these cap screws fits my socket wrench perfectly, and the yellow zinc finish looks like it’ll hold up well in my shop. They drove in smoothly without any binding, exactly what I needed for a machinery repair.

The yellow zinc finish on these partially threaded cap screws looks sharp and resists rust better than the plain steel ones I usually grab. Used them to secure a heavy motor mount, and the hex head took a socket drive without stripping at all.

These L9 alloy steel bolts fit perfectly into our heavy press jig, and the yellow zinc finish feels robust against oil and dirt. The partial threading made alignment much easier than a fully threaded bolt would have.
