Emma ★★★★★

The yellow zinc finish on these Grade L9 screws is holding up perfectly on my tractor attachment, no rust after a week of rain. Took a socket to them and they seated flush every time.

Daniel D. ★★★★☆

The yellow zinc finish held up fine during assembly, and the threads cut cleanly with no binding. Only gripe is the 100-count box doesn't include a small tray, so I had to keep them in the bag to avoid spills.

Victoria W. ★★★★☆

I’ve been using these for a few heavy-duty projects and the hex head really grips well with a ratchet, no stripping. Only wish they came in a slightly longer length for deeper assemblies, but for standard fastening they do the job.
