Amelia K. ★★★★★

I needed a strong bolt for a repair on an industrial press, and these partially threaded screws gave me the grip I needed without bottoming out. The hex head fit my socket perfectly and the yellow zinc finish is holding up well in a dirty shop.

Jacob ★★★★★

These bolts fit perfectly in my trailer hitch build and the L9 alloy steel feels incredibly tough. The partial threading made aligning the joint much easier than a fully threaded bolt would have.

Brian ★★★★☆

The yellow zinc coating looks great and seems like it will resist rust well on my shop equipment. I used a socket to drive them and the hex head held up perfectly without stripping. Only wish they came with a few washers in the pack.
