Ryan ★★★★★

The yellow zinc finish on these Grade L9 bolts is holding up great in the shop, no rust after a few weeks of exposure to cutting oil. Partial threading made alignment a lot easier when I was bolting down my press base. Fit my 5/8 socket perfectly right out of the box.

Isabella ★★★★★

Pulled the old ones off my planer and these threaded in smooth like butter. The L9 alloy steel feels way tougher than the hardware store stuff.

Madison T. ★★★★★

Used a couple of these to bolt down a heavy motor mount, and the hex heads grabbed my socket perfectly without stripping. The yellow zinc finish looks solid and the partial threading gave me just the right grip for a snug fit against the frame. For 25 pieces at this grade, that’s a solid value.
