براغي رأس سداسي 5/8-11 × 3-1/4" | فولاذ درجة 5 زنك أصفر | خيط جزئي (25/عبوة)

I needed these for a heavy-duty welding jig I’m building, and the hex head took a socket wrench beautifully—no stripping. The yellow zinc coating looks tough and should resist rust well in my shop.

The partially threaded design grabbed the threads perfectly when I bolted these onto my press frame, and the grade 5 steel feels solid under a wrench. The yellow zinc coating is holding up fine so far, no rust after a week of shop use.

The yellow zinc finish looks great on my project, and the partial threading made it easy to get a tight grip without stripping. These hold firmly under moderate torque—just what I needed for mounting a motor.
