براغي رأس سداسية 1 بوصة-8 × 3-1/2 بوصة | صناعة أمريكية | فولاذ سبائكي من الدرجة L9 مطلي بالزنك الأصفر | ملولبة جزئياً (10 / عبوة)

The yellow zinc coating on these L9 bolts is holding up great on my press, no rust after a week in the shop. They threaded cleanly into the tapped hole and the hex head fits a standard wrench perfectly.

The partial threading made all the difference when I needed to bolt down a heavy motor mount—no wasted grip length fighting a full thread. They drove in smooth with a socket and the zinc coat still looks factory-fresh after a few months in my shop.

Put these on my big trailer hitch after the old bolts started rusting. The USA-made L9 alloy steel feels a lot tougher than the grade 5s I'd used before, and the yellow zinc finish is a nice touch for weather resistance.
