براغي رأس سداسي 9/16-18 × 5-1/2 بوصة | فولاذ درجة 5 مع زنك أصفر | ملولبة جزئيًا (25 / عبوة)

Needed some longer bolts for a shop press project, and these 5-1/2" grade 5 screws were exactly what I was after—the partially threaded section made them ideal for clamping down thick plates without binding, and the hex head grabbed my socket perfectly.

The yellow zinc finish is holding up nicely so far, and the partial threading makes them perfect for bolting down our jig table without bottoming out early. Sockets grabbed the hex head cleanly on all 25, so no stripped corners during install.

These bolts were exactly what I needed for a heavy equipment assembly; the partial threading made it easy to start the nut by hand. The hex head had a good grip in my socket, and the 5-1/2 inch length was spot on for my application.
