براغي رأس سداسي 3/8-16 X 4-3/4" | فولاذ درجة 5 زنك أصفر | خيط جزئي (50 / عبوة)

The yellow zinc finish on these Grade 5 bolts looks even better in person, and the partial threading grabbed perfectly when I torqued them down on my press frame. All fifty came in the box with clean, consistent threads. These are my new go-to for heavy equipment repairs.

The threads cut clean without any binding, and the yellow zinc finish looks uniform across all fifty pieces. I’ve got them holding a motor mount and they haven’t budged a hair under vibration.

I needed these for a heavy bracket assembly and the Grade 5 steel feels much more solid than the cheaper hardware I've used before. The hex head fits my socket perfectly without slipping, and the partial threading makes lining everything up much easier. Really glad I grabbed a 50-pack for future pro
