Sophia J. ★★★★★

The threads cut clean and the yellow zinc finish looks even across all 25, which made torquing them into our assembly jig straightforward. Fully threaded length gave me plenty of grip for a 1-1/2" fit, and the hex head seated solidly in my socket wrench.

Thomas ★★★★★

Just got these for rebuilding a small press at the shop, and the yellow zinc finish is spotless across all 25 pieces. The threads are clean and ran into the tapped holes without any binding, which is more than I can say for some cheaper packs I've used.

Eva ★★★★★

I needed some heavy-duty bolts for a trailer attachment, and these L9 alloy steel screws handled the torque without stripping. The threads are clean and consistent, and the 25-pack is enough for multiple projects.
