براغي رأس سداسي 3/4-16 × 4-1/2 بوصة | صناعة أمريكية | درجة L9 من سبائك الفولاذ مطلي بالزنك الأصفر | ملولبة جزئياً (20 / عبوة)

The hex heads fit my socket perfectly without any wobble, and the threaded portion was just long enough for the heavy bracket I was mounting. These bolts feel seriously solid for the price, especially being USA-made alloy steel.

Took a chance on these for a heavy equipment repair and the 3/4-16 threads started perfectly by hand. The partially threaded design gave me just enough shank length to clamp down the assembly without binding.

The yellow zinc coating on these Grade L9 bolts held up perfectly during a tight installation, no galling at all. The partial threading made cinching down a bracket much quicker than I expected.
