Installed these on a heavy press at work and the partial threading made alignment much easier than expected. The L9 alloy steel feels like it’ll handle the torque without stripping.

Just installed these on a heavy-duty press jig and the yellow zinc held up better than the cheaper bolts I'd used before. The partial threading made alignment way easier than I expected for a 6-inch screw.
