Violet H. ★★★★★

The yellow zinc finish on these Grade L9 bolts matched perfectly with my existing hardware, and the 4-1/2" length was spot-on for my equipment mount. They threaded cleanly into the tapped holes without any binding.

Jason S. ★★★★★

Needed some partially threaded bolts for a project and these fit the bill perfectly with that Grade L9 alloy steel giving me confidence they'll hold up under load. The yellow zinc coating looks clean and the hex heads seated nicely with my socket wrench.

Scarlett K. ★★★★★

The hex head on these cap screws grabbed my socket perfectly without slipping, and the yellow zinc coating looks like it'll hold up well in my shop equipment. Exactly the partially threaded design I needed for a snug fit.
