براغي رأس سداسي 1/4-28 × 3/4 بوصة | صناعة أمريكية | سبائك فولاذ درجة L9 مطلي بالزنك الأصفر | ملولبة بالكامل (100 / عبوة)

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.

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.

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.
