براغي رأس سداسي 5/16-18 × 1-3/8 بوصة | صناعة أمريكية | فولاذ درجة 8 بطلاء زنك أصفر | خيط جزئي (100 / عبوة)

The partially threaded design is a lifesaver when you need a firm bite before cinching down on a heavy bracket. The yellow zinc finish looks clean and the threads engaged smoothly with my socket; these held up without any stripping during assembly.

I needed a full set of Grade 8 hardware for a heavy-duty jig I’m building, and these hex head cap screws with the partially threaded design were exactly what I needed—they grip securely without bottoming out.

I needed some strong fasteners for a trailer hitch repair and these grade 8 bolts held up perfectly under the torque. The partially threaded design made installation a lot easier than dealing with fully threaded ones.
