3/8-16 × 2-1/2 بوصة براغي رأس سداسي | درجة 5 فولاذ مع زنك أصفر | خيط جزئي (400 / عبوة)

Bought these for a small equipment frame I'm building, and the partially threaded design made aligning everything much faster than fully threaded ones. The yellow zinc coating looks consistent and should resist rust out in the shop.

I needed a batch of sturdy fasteners for some heavy equipment repairs, and these Grade 5 screws with the yellow zinc coating are holding up perfectly so far. The hex head drives cleanly with a socket, and the partial threading made alignment effortless on my assembly.

The partial threading is a huge time-saver when I need to clamp two pieces together without rattling, and the yellow zinc finish has held up beautifully in a damp shop. 400 pieces means I won't be reordering for a long time, which is exactly what I was hoping for.
