براغي رأس سداسية مقاس 3/4-16 × 2-1/4" | صناعة أمريكية | فولاذ سبائكي درجة L9 مطلي بالزنك الأصفر | كامل السن (20/عبوة)

I’d been hunting for a fully threaded 3/4-16 in this length for ages, and these L9 alloy steel bolts torqued down cleanly without stripping. The hex head sat perfectly in my socket, and the yellow zinc coating hasn’t shown a speck of rust after a week of sweaty shop use.

The yellow zinc finish on these is holding up perfectly in a slightly damp basement shop, no rust after a month of use. They thread smoothly into existing tapped holes without any binding. Exactly the heavy-duty grip I needed for securing a motor mount.

Installed these on a heavy-duty press assembly and the Grade L9 alloy held torque perfectly without stripping. The yellow zinc coating looks clean and should resist corrosion well around the shop.
