براغي رأس سداسي 3/8-16 × 3" | فولاذ درجة 5 زنك أصفر | خيط جزئي (325 / عبوة)

The hex heads grabbed my socket perfectly without any stripping, and the yellow zinc finish on these grade 5 bolts looks clean and durable. I used them to secure a heavy-duty machine base and they've held tight under vibration. Exactly what I needed for a solid industrial fastening job.

Needed a bunch of these for rebuilding a hay baler and the yellow zinc coating looks like it'll hold up better out in the weather than plain steel. The partial thread makes them grip tighter in the frame while the unthreaded shank slides through the mounting holes clean.

Needed a strong bolt for a shop press rebuild, and these grade 5 hex heads tightened up perfectly without stripping. The partial threading made alignment with the frame holes much easier than fully threaded bolts would have.
