براغي رأس سداسي 5/8-11 × 3-3/4" | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (25 / عبوة)

The partially threaded design made installation a breeze on my press brake—the hex head grabbed securely with my socket. These are solidly built and the yellow zinc coating looks clean. Exactly what I needed for a heavy-duty industrial fix.

Used these to fasten a heavy-duty gearbox bracket and the grade 5 yellow zinc held up perfectly under torque without any galling. The partially threaded shank made alignment much easier than fully threaded bolts I've tried before.

These bolts threaded in cleanly and snug using just a standard socket, no binding at all. The yellow zinc finish looks solid for industrial use and should resist rust well.
