براغي رأس سداسي #5/16-24 X 5-1/2" | فولاذ درجة 5 زنك أصفر | ملولب جزئيًا (50 / عبوة)

I needed some longer bolts for a machinery repair and these 5-1/2" hex heads fit perfectly with my socket wrench. The yellow zinc finish looks decent, though I wish they were fully threaded like the originals.

The threads are clean and the yellow zinc finish looks evenly applied across all fifty. I used these for a jig assembly and the partial threading made setup a lot quicker since the smooth shank seated perfectly.

Bought these for a farm implement repair and the partially threaded section made alignment much easier than fully threaded bolts. The yellow zinc coating seems decent and should hold up fine here. Only minor gripe is the hex head is a bit shallower than I expected.
