براغي رأس سداسية مقاس 3/4-10 × 5-1/2" | صناعة أمريكية | فولاذ سبائكي درجة L9 زنك أصفر | خيط جزئي (20 / عبوة)

The yellow zinc finish is holding up great on these—no rust after a week of outdoor use on my trailer hitch. The partial threading made alignment a lot easier than I expected for this size bolt.

The hex head on these cap screws grabs the socket perfectly, and the yellow zinc finish looks clean on my industrial frame. They're beefy enough for heavy machinery assembly, and the partial threading made installation quicker than I expected.

Finally got around to replacing the bolts on a press that's been missing them for years. The Grade L9 steel feels seriously heavy duty and the yellow zinc coating looks like it'll hold up way better than the old rusted ones.
