Customer Reviews (4.8 / 5 · 5 reviews)

Richard ★★★★★

The yellow zinc coating on these hex head cap screws is holding up well against rust in my damp shop. They thread smoothly into the tapped holes without binding, and the Grade L9 alloy steel feels plenty tough for heavy equipment assembly.

Jason P. ★★★★★

I was pleasantly surprised by the uniform plating on these—the yellow zinc coating looks even and nothing was stripped when I torqued them down. The fully threaded design made them easy to work with on a jig setup.

Robert D. ★★★★★

Used these to secure a motor mount on my milling machine, and the grade L9 alloy held up perfectly under vibration. The yellow zinc finish looks clean and hasn't shown any rust after a few weeks in a damp shop.
